More Strength, Less Weight The automotive industry is continuously exploring new technologies to facilitate the increasing demand to reduce emissions while simultaneously improving performance. Through collaborations across the steel supply chain, progress of these advancements has been successful to stay above the threshold. One of these advancements is the development of High Strength Low Alloy […]

Flat rolled steel products can be separated into two general categories: plate mill products and hot strip mill products (coils). The processes to create these products have differences, but fundamentally the same principles drive production. Heating and cooling is used to obtain a specific microstructure, which gives steel its mechanical properties. Plate Mill Products (often

Wear, the undesired removal of material from contacting surfaces, is an extremely common phenomenon – tires, clothes, shoes, coins, floors, even the Earth experience wear. Unlike stress, wear is visible. It’s predictable. But inevitability doesn’t mean that we don’t have ways to combat it. Many steel parts are designed to withstand stresses; increasing strength increases

Medium and high carbon steels have large concentrations of a secondary phase in steel known as iron carbide (Fe3C).   Iron carbide precipitates out in dark lamellar plates like in FIG 1.  These plates increase strength and reduce formability by acting as barriers to dislocation movement during stamping, rolling, pressing, and bending- which can lead to

There are many steps in the process of turning a steel coil into a finished part. One of those steps is forming the shape of the part, and the two most popular methods for this are stamping and cutting. This article will focus on laser cutting. Cutting Basics There are three types of cutting: laser

The creation of the mini mill brought flexibility to the steel market. Melting scrap instead of consuming raw materials allowed for reduced capital requirements, less dependency on site location, and operational ease starting and idling the furnaces. But the question is: how do the steel products of mini mills stack up against the products of

Many applications, primarily those that involve welding, have a “carbon equivalent” requirement. The carbon equivalent, or CE, is a number generated from an equation that relates alloying elements to a percentage of carbon. In steelmaking, the properties of the steel are determined by many inputs. Cooling rate, carbon percentage, alloying elements, and many other variables

Reel breaks are raised bumps or kinks that go across the width of a steel coil or plate. If present, they are usually at the very OD/ID (depending on processing) of the coil, but if severe, they can continue for several laps into the body of the coil. Reel breaks are a consequence of coiling
