An important trend in metallurgy today is the transition from ordinary steel grades to high-strength grades (thermo-mechanically hardened, hardened, dual-phase, hardenable by dry coating, etc.). This is especially evident in the automotive industry, where ever-increasing safety and fuel economy standards are forcing manufacturers to develop lighter, greener and more reliable machines. Conventional high-strength (HSS) and advanced high-strength (AHSS) steels have increasingly replaced their soft counterparts in car bodies over the past decade. A typical modern car contains about 30% HSS and 30% AHSS with a further downward trend in the proportion of “soft” low carbon low alloy steels. The development of rolled steel for the automotive industry is carried out under the auspices of the International Iron and Steel Institute and other specialized associations.
