Steel Types

Manufacturers and users of steel products generally understand the fundamental metallurgy of conventional low- and high-strength steels. Section 1.C provides a brief description of common steel types. Since the metallurgy and processing of AHSS grades are somewhat novel compared to conventional steels, they are described here to provide a baseline understanding of how their remarkable mechanical properties evolve from their unique processing and structure. All AHSS are produced by controlling the cooling rate from the austenite or austenite plus ferrite phase, either on the runout table of the hot mill (for hot-rolled products) or in the cooling section of the continuous annealing furnace (continuously annealed or hot-dip coated products).  In the page links following you can find information about the most common types:
