An estimated 3,500 different grades of steel currently exist, with about 75 percent of them developed in the past 20 years. And more than 500 sheet aluminum alloys are registered with the Aluminum Association. Each of these materials grades has a different chemistry and different tensile properties...

Before a manufacturer can figure out what’s wrong with metal that keeps splitting during a forming process, it needs to understand just why one batch of sheet metal differs from another. The first step is learning the lingo associated with metal creation.

Many in the metals industry think that stiffness and strength are the same thing. That's not the case, especially when you are talking about metals used in automotive designs.

The microstructure of advanced high-strength steels (AHSS) can be tailored to produce specific properties that are engineered for each application. This is why usage of AHSS grades is growing in the automotive industry, and dual-phase (DP) steels are leading the way.

Advanced high-strength steels are made differently in the steel mill, and they need to be processed differently in part manufacturing. WorldAutoSteel released forming and welding guidelines intended to help the users of these products work through the differences.

Challenges faced by stampers in the quest to produce a robust part are magnified when they form high strength steels. As materials increase in strength, the inherent tensile property variability increases. Using products from the family of grades known as the advanced high-strength steels (AHSS) complicate matters even more, since what is supplied from one mill may not be produced in the same way as that from another mill. Understanding how steel is made sets the stage for a more profitable relationship between the steel supplier and the steel consumer. The certified steel properties that come with the coil are useful, but more information about the sheet metal increases the likelihood of success.
