Manufacturers across the upstate strive to create everything from cars and airplanes to engines, with their goods shipped across the country and around the world. Often, these manufactured products are carefully assembled with metal parts that are cast, fabricated or cut. Due to its strength, steel is the material of choice for these products. Several companies here in the upstate provide these companies with the Steel fabrication – manufacture various components needed to create the cars we drive, the buildings where we work and the infrastructure we need.

Provide the products needed for construction

One of these companies is Kloeckner Greenville, the upstate branch Kloeckner Metals Company. The company, listed on the German stock exchange, manufactures and distributes steel and metal products. In 2017, it announced its investment of $ 11.3 million to expand its manufacturing facility at 1 White Horse Road, The Northern State Business Journal Previously reported. Greenville County received $ 100,000 from the Economic Development Co-ordinating Council to help cover site preparation costs.

This expansion included a 50,000 square foot bay with 43 ton cranes and a new highly automated slitting line fully capable of processing advanced high strength steels and aluminum.

Kloeckner Metals bought Mac Steel in 2011, which included its Greenville plant.

“South Carolina’s world-class workforce continues to demonstrate an unmatched level of excellence and as a result companies like Kloeckner Metals continue to grow and prosper in our state. I congratulate this great company and look forward to everything we know it will achieve in Greenville County ”, Governor Henry McMaster said at the time.

The company ships carbon and non-ferrous metals from inventory held at its 42 locations across North America.

The 200,000 square foot White Horse Road facility serves Kloeckners customers across Georgia, Florida, North Carolina, South Carolina, Virginia and Tennessee, according to the Kloeckner website. . The Greenville plant employs approximately 85 workers.

Kloeckner Metal Corporation’s sales are about 7 billion euros, or about $ 8.3 billion, according to Bob DeMarco, executive vice president of Kloeckner. In North America, the company’s sales are approximately $ 3 billion.

“The Southeast has grown over the past 20 years or so as manufacturing has moved south,” DeMarco said. “South Carolina and our Greenville site have certainly benefited from this migration. “

In its facilities, the company cuts, cuts to length and sells coils. “And we sell various long products in a lot of markets – long products being beams, channels, angles, rounds, squares, plates, plates, tubes, pipes, stuff like that,” he said. declared DeMarco.

Many of Kloeckner’s customers work in the HVAC and automotive manufacturing industries and use these steel parts to make their own products.

The results of the pandemic

While other industries have suffered from the novel coronavirus pandemic, DeMarco said Kloeckner Metals has not seen a significant impact. “Business has not fallen to the level that we initially thought it would,” he said.

During the economic shutdown, Kloeckner, like many manufacturers, was not ordered to shut down.

“At our 42 locations, we have been rated as critical in all of the states in which we operate,” said DeMarco. “Fortunately, we haven’t had any locations closed for a while due to COVID. We have strong policies in place to protect our employees, to protect our customers. “

Around 83,000 employees worked in blast furnaces and steel mills that produced steel for companies like Kloeckner Metals in 2019. Source: Statista.

While DeMarco said trade industry data showed business was down about 30% when the pandemic started around April, it is now down about 15%. The company had to downsize in some places and switch to four-day work weeks, but DeMarco said the company was “on the rise.”

“It wasn’t a V-shaped recovery, but you can see it like the Nike swoosh, right? So here is that bottom of the V, and then it started to come up, then halfway, maybe a little more than halfway, ”DeMarco said.

The situation of steel production

The entire steel industry has suffered due to COVID-19 in what Barron reported was “obvious and some means not so obvious”. The sector has had to contend with a drop in demand as some automotive and construction projects are halted, but steel prices have risen. In May, scrap metal prices rose 13% from a year ago, according to the outlet.

Steel production has changed for years. The pandemic, DeMarco said, has hit factories producing hard steel – due to the closures Barron’s mentioned.

Structural fabrication refers to the cutting, bending and joining of steel to create different products. When fabricating metal frames, several pieces of steel are combined to form different structures of predefined sizes and shapes for assembly in buildings, industrial equipment, tools, and various other end products. Source: Kloeckner Metals Corporation

“I have been in the steel business for 34 years now. And that has been a problem for my entire 34 years: overcapacity in steel production, ”said DeMarco. “Many countries have built factories… to try to do something about their employment situation.”

However, he continued, whenever one was built somewhere, another elsewhere was closed.

Even when a pipe and tube producer or manufacturer obtains their material from a reliable source, checking metal alloys using technologies such as LIBS, OES, and XRF is a good idea to avoid material mix-ups. Image provided by Thermo Fisher Scientific

Advances in technology are making many tools smaller, faster, and easier to use, and so are materials identification instruments used in the production and fabrication of tubes and pipes. Mobile optical emission spectroscopy (OES), portable X-ray fluorescence (XRF), and portable laser-induced breakdown spectroscopy (LIBS) are all examples of portable instruments with the power to perform laboratory analyzes on field. . Portable elemental analyzers allow users to test materials on the shop floor in seconds to determine their elemental composition, verifying that the metal used in production meets required specifications.

Positive Material Identification (PMI) capability helps mitigate risk and improve productivity, but it can be difficult to determine which of these three analytical techniques is best for tube and pipe producers and fabricators. . An overview of how OES, XRF, and LIBS systems work, and the benefits they offer tube and pipe manufacturers, can go a long way in making a sound investment in equipment.

How they work

A non-destructive test, XRF irradiates the test sample with high-energy X-rays produced by a miniaturized X-ray tube in the instrument. This causes the atoms in the sample to emit secondary (or fluorescent) X-rays specific to the elements present in the sample. The instrument’s detector measures and analyzes these characteristic secondary X-rays to determine their chemical identity and concentration in the metal being tested. This capability makes XRF useful for qualitative and quantitative analysis of the composition of materials.

Rather than emitting X-rays like an XRF analyzer, OES instruments send out a high voltage electrical pulse to excite atoms in a sample. The sample then discharges an arc spark which can be measured and analyzed by a spectrometer in the OES unit. From there, the OES system determines the chemical composition of the sample being tested.

LIBS analyzers ablate the surface of the sample with a highly focused laser, which produces a plasma composed of electronically excited atoms and ions. These atoms begin to decay in their ground states and emit wavelengths of light, unique to each element, which are analyzed by a spectrometer in the LIBS device. As with XRF, LIBS analysis can be used for both quantitative and qualitative measurements.

Of the three, XRF is the only one classified as non-destructive; OES and LIBS are minimally destructive in that they leave a scorch mark on the sample.

Productivity considerations

Considerations to keep in mind when choosing a basic analyzer include portability, measurement speed, and ease of use.

Portability can have a substantial impact on productivity. Both LIBS and XRF are available as lightweight portable analyzers, with some LIBS units weighing as little as 6 pounds. This means that analysis can be performed anywhere in the factory or warehouse, as well as in hard-to-reach areas in the field. A mobile OES can weigh up to 80 pounds and requires a cart.

Factors that contribute to speed and ease of use include:

Sample preparation – Mobile OES and LIBS generally require sample preparation as even traces of contaminants such as grease, paint and oxidation can lead to unreliable results. Sample preparation involves cleaning and grinding a square inch of test area on the metal. XRF rarely requires sample preparation.

Instrument configuration – XRF is point-and-shoot technology that does not require daily setup. Daily setup of LIBS is relatively minimal, requiring a two-step process that takes approximately 10 minutes. Daily setup of the OES requires several steps and 15-20 minutes, and both instruments require regular cleaning.

Analysis speed – Depending on the material tested, the advanced LIBS and OES analyzers can test most samples in about 10 seconds. This includes materials in which the carbon content is of interest. An XRF analyzer, for most materials, can identify and provide the chemistry of many types of alloys in 3-5 seconds. However, this does not include carbon analysis, and the analysis time may increase slightly if other light elements are present in the alloy. A few seconds may not seem like a lot of time, but seconds add up quickly in situations that may require multiple average readings or when multiple samples need to be analyzed. Therefore, choosing the right technology is important for any application where higher throughput is the goal.

Hardware considerations

Tube and pipe producers and manufacturers need to consider more than just productivity when choosing an elemental analyzer. The three technologies differ in their analytical capabilities, so it is important to match the capabilities to the materials to be tested.

LIBS and OES are both useful for differentiating alloys and quantifying carbon concentrations in low alloy steels, carbon steels, and stainless steels. This includes the low carbon content of L grade stainless steels.

XRF provides rapid chemistry and quality verification of incoming raw materials and final products, and it can be used for composition analysis and to measure the thickness of alloy coatings. In the case of steel pipes, for example, a coating can be applied to prevent oxidation during storage and transport or to facilitate the application of paint. The ability to analyze coating layers helps ensure quality control and reduce coating waste.

Often, XRF and LIBS may be required to perform extensive quality control of end products. These complementary devices can be used throughout the production process, from testing of incoming materials to outgoing quality assurance or quality control of finished tubes, pipes and assemblies.

Trust but verify

As the industry continues to globalize, many tube and pipe producers and manufacturers increasingly purchase materials from overseas, and these may include new suppliers that they have not worked with before. . Unfortunately, material test reports may not always be accurate. A trust but verification approach is therefore necessary to confirm the composition of the material sent by the supplier. This is where analytical technology comes in.

Inexperienced or unreliable vendors may try to keep costs down by not performing PMI in-house, or they may not use an outside testing lab to verify the equipment they ship. The consequences of mixing materials can range from end user rejection to catastrophic failure that can result in injury or even death. For example, using an inferior material in a critical application, such as an aircraft engine, puts the safety of everyone on board at risk. By exercising due diligence in performing the PMI on site, pipe and tube producers and manufacturers can go a long way in protecting their reputation and their business. Using elemental analysis to quickly spot problems avoids the costly problem of determining that products have been developed out of specification after adding value during the production process. Often the manufactured part or assembly must be completely scrapped.

Checking materials does not stop at entry control. Supervisors and those responsible for quality control must ensure that the right materials are used throughout the production process, so best practices require PMI at every stage of production. Highest compliance uses a testing protocol that follows the part, assembly, or equipment through the production process until final validation.

For critical components, a PMI should be the first step upon receipt of shipment, and inspections should continue to the point of installation. For facilities prior to the inspection process (for example, a 30-year-old refinery), performing a thorough validation may require a shutdown to verify the integrity of components and assemblies that were not submitted. to adequate tests before installation. Full use of PMI technology today may prevent such drastic action in the future.

Updated January 2021

The Advanced digital design and manufacturing lab (ADDFab) is available to academic institutions, industry and the local community.

ADDFab has three main goals to serve this diverse customer base: (1) design and print superb metal and polymer parts, (2) support academic research, and (3) provide training and education opportunities.

1. Design and print great parts

Two metallic printers use fine metallic powders to build parts as large as 25x25x30cm with details as fine as 250um. The EOS M290 is a powder bed system that uses Direct Metal Laser Sintering (DMLS) to build parts layer by layer while the LENS 450 is a Directed Energy Deposition (DED) system that deposits lines of metal and can produce parts from custom metal alloys.

Three polymer printers cover three different printing technologies. The EOS P110 is a nylon powder bed printer that uses selective laser sintering (SLS) to produce parts. It has a build area of ​​23x20x30cm and can produce details as fine as 250um. The main advantage of the SLS process is that it does not require support structures for the overhanging parts, so it can easily print extremely complex and delicate geometries. EOS-P110The Connex350 is a multi-material printer that can print flexible and rigid materials in one piece, and even mix materials to adjust material properties and colors. Markforged printers extrude nylon filament in a fused filament manufacturing (FFF) process and can print in chopped carbon fiber infused nylon (Onyx) or incorporate a continuous strand of fiberglass, Kevlar, or carbon fiber in each layer.

For customers who need technical or design assistance to prepare parts (or ideas!) For printing, we offer engineering advice on an hourly basis with undergraduates or experienced engineers.

2. Support university research

ADDFab facilities are available for use as a department where our staff does all printing, but also for dedicated use on a daily or weekly basis. Training is available where students and faculty can learn how to operate the equipment and then use it to conduct their own additive manufacturing research.

We also provide printing services and technical support to faculty from all university departments.

3. Training and education opportunities

ADDFab supports undergraduate and graduate courses in additive manufacturing by printing parts, offering tours, and training students in the use of the equipment. We also work in partnership with student groups and high schools.

For industry and the local community, ADDFab is organizing a series of workshops on additive manufacturing. These are intended to broaden the understanding of how 3D printing will affect the manufacturing industry and to provide practical skills using industrial grade 3D printing technology. Both types of courses are offered throughout the year.

If you have any questions on how to work with ADDFab on a future project, please contact us at addfab@umass.edu. We can’t wait to work together!

Grade 416 stainless steel is a martensitic machining bar, with improved sulfur and phosphorus machinability. This steel is sometimes used in the hardened state or not and strongly tempered, because it has a low cost and is easily machinable. Grade 416 is delivered as a bar.

Image Credit: Shutterstock / Alexandru Rosu

Martensitic stainless steels are designed for high hardness and other properties are compromised to some extent. Their useful operating temperature range is limited by their loss of ductility at subzero temperatures, and loss of strength through superheating at high temperatures.

Compared to common austenitic grades, these steels have lower corrosion resistance. They have resistance to fresh water, dry atmospheres, and mild alkalis and acids, but comparatively less strength than equivalent non-turning grades. Machining grades without high sulfur content, such as 416, are not suitable for marine or other chloride exposure. To achieve maximum corrosion resistance, the steel should be in a hardened condition with a smooth surface finish.

Grade 416 has good resistance to scaling in intermittent service up to 760 ° C and up to 675 ° C in continuous service. It is not recommended for use at temperatures above the appropriate tempering temperature.

Hot work – All hot work processes should be performed after uniform heating to 2100-2250 ° F (1149-1232 ° C). Hot work below 1700 ° F (927 ° C) may cause cracking.

Machinability – The metal offers excellent machinability. It has the highest of any commonly available stainless steel, at around 85% that of a free-cutting carbon steel. Machinability is best achieved in a subcritical annealed condition.

Heat treatment – Complete annealing by heating at 815-900 ° C for ½ hour per 25 mm thickness. This is followed by cooling at 30 ° C / hour maximum up to 600 ° C and air-cooled.

Subcritical Annealing – The material is heated to 650-760 ° C and air cooled.

Hardening – Grade 416 can be hardened by heating to 925-1010 ° C, oil quenched and tempered to meet mechanical requirements.

Condition: The range of tensile strength (N / mm² or MPa) QT 650: 650-850

  • QT 900: 900-1050
  • QT 850: 850-1000
  • QT 700: 700-850
  • QT 800: 800-950

Weldability – The weldability is bad. If necessary, low hydrogen grade 410 electrodes can be used. It can be preheated to 200-300 ° C, which is followed directly by an annealing or re-hardening process, or expansion to 650-675 ° C. If the weld does not need to be hard, a grade 309 austenitic stainless steel filler rod can be used.

Applications

The fields of application of grade 416 martensitic stainless steels are the following:

  • Machined parts with automatic screw
  • Washing machine parts
  • Valve parts
  • Gears
  • Pump shafts
  • Motor shafts
  • Studs
  • Bolts and nuts

The stunning Vanishing Point frame by Tonic Fabrication is another of our recent series of really nice all-black bikes (there are more on the way too), in this case, handcrafted from a mix of tubes. in Columbus Zona steel and True Temper OX Platinum in Portland Oregon.

Almost everything about Vanishing Point is interesting. For starters, while this is steel and, by modern standards, a relatively unusual tubing mix, it’s not about producing some sort of retro tribute. Retro bikes don’t come with oversized steerer tubes. It’s also not an attempt at a super light racing bike (the frame weight is 1.9kg and the Enve fork brings it to 2.4kg). Instead, it’s all about the ride. Tonic describes the frame as being perfectly suited for sports, leisure and commuting.

That said, ours was built with a pretty fancy kit that keeps the overall weight at a fairly light weight of 8.4kg, and the oversized steerer tube, short chainstays, and deep section downtube all tell us a bit. Rigid and efficient pedaling platform. . So the Vanishing Point might be made of steel, but it’s not a retro road bike exercise.

Tonic are Landon and Tony who, after working as frame builders for other bicycle manufacturers, went out on their own a few years ago. They started with two jump bikes – the Fall Guy and the Howie – then followed with a fixed – the Supernaut – then a “cross bike”, and now their first road bike – the Vanishing Point. These guys believe in the benefits of large diameter steel tubes, angled top tubes, and short chainstays – which are a hallmark of all of their frames, although they offer full personalized service, you can take it to the next level if you want to. wish.

Our bike is built by Tokyo fixed with a very chic Enve Road 2.0 carbon fork, (you can also have the Tonic Steel Fork on request) a SRAM Force groupset, Easton EC90 SL wheels, Easton EA70 stem and handlebar, and a Fizik Antares saddle, but the process construction offered by Tokyo Fixed and Tonic is fully customized so that you can take things in the direction you want. Rack and guard mounts are production options as well as custom frames for those looking for a high-end fast audax / commuter bike – but not with this Enve fork.

Tokyo Fixed sells the frameset for £ 1,300, including the Enve fork – which is a sum of money in itself – and Tonic’s semi-integrated headset setup. The build we have will set you back £ 4,100 with the Easton EC90 wheels being a big part of that. If that’s not high-end enough for you, there’s a stainless steel version on the way.

So what’s going on with those big tubes and the mixture of steels. In terms of performance, what do they bring to the party at Vanishing Point? I’ll let Tony from Tonic explain:

“As for the tube used, we select it based on diameter, wall thickness, bead profile and intended use (no magic bullet here). But we always preferred the aesthetic. and ride quality from big constant diameter tubes to award winning tubes The 38mm tub is a staple of almost every Tonic and for the Vanishing Point it is paired with our 22.2mm Supernaut base creating a very stiff, without sacrificing the high ride quality of a modern steel road frame. “

You can see why we can’t wait to throw a leg up on this baby. On paper at least, the geometry seems designed to provide a stable but still lively ride, parallel to 73 ° in medium sizes with the seat tube relaxing slightly to 72.5 ° in larger sizes while the seat tube. steering sharpens to 73.5 ° in the larger model while the seat tube suddenly relaxes to 72.5 °. All the main tubes vary in length depending on the size, including the bases which range from 405 to 410mm, and everything is put together beautifully.

And the name, Vanishing Point? Inspired by the perspective trick involving parallel lines first employed by Renaissance painters, or the 1971 film Vanishing Point with Barry Newman as Kowalski, an all-American anti-hero on a benzedrene-fueled cross-country race to destruction behind the wheel of a Dodge Charger or similar?

No, it’s not going to be Renaissance painters, is it? In fact, the Vanishing Point was almost called The Kowalski, but the guys at Tonic figured hardly anyone would tie it in to the movie. Hoping that the ride is just as exciting, but without the same end as the film (without wanting to spoil it for anyone … the film which is).

The Incoloy 825 is very resistant to corrosion. It has a high nickel content, sufficient to resist chloride ion stress corrosion cracking, and a very stable austenite structure. The molybdenum and copper contents allow the alloy to resist reducing agents and acids. Chromium confers resistance to oxidizing conditions, such as nitric acid solutions, nitrates and oxidizing salts. The alloy is titanium stabilized to resist pitting and intergranular attack after fabrication, particularly welding, which includes heating to the critical sensitization temperature range (650 ° C – 760 ° C).

Alloy 825 offers exceptional resistance to corrosion by sulfuric and phosphoric acids and is often the most cost effective alloy for sulfuric acid service.

Austral Wright Metals can supply this alloy in the form of plate, sheet, strip, bar, rod, wire, tube, pipe, fittings, fasteners.

Pressure vessels

The Incoloy 825 is approved for operating temperatures of pressure vessels up to 525 ° C (AS1210, AS4041), 538 ° C (ASME Boiler & Pressure Vessel Code, Sections I, III, VIII, IX, Cases 1936, N-188). Brittle phases can form in Alloy 825 at temperatures above ~ 540 ° C, so it is not normally used at these temperatures, where creep failure properties would be design factors.

Applications of Incoloy 825

Typical applications of the Incoloy 825 alloy include:

Corrosion resistance

The exceptional property of Incoloy 825 is its corrosion resistance. Under reducing and oxidizing conditions, Incoloy 825 is resistant to general corrosion, pitting and crevice corrosion, intergranular corrosion and stress corrosion cracking. It is particularly useful in sulfuric and phosphoric acids, flue gases containing sulfur, acid gases and oil wells and seawater.

Figure 2. Laboratory pure sulfuric acid isocorrosion table.

Manufacturing

The Incoloy 825 can be easily worked hot or cold. Hot work should be between 870 and 1180 ° C, to finish between 870 and 980 ° C. For maximum corrosion resistance, hot worked parts should be stabilized and annealed before use. The alloy is easier to cold form than stainless steels.

Machinability

The Incoloy 825 is classified as a “C” alloy and is relatively easy to machine.

Welding

The alloy is easily weldable by normal processes (GMAW (MIG), GTAW (TIG), SMAW (manual), SAW). The joint must be clean to avoid contamination of the weld pool.
