The aim of this paper is to present the basic concepts of advanced high strength steels (AHSS) for use in the automobile industry, including chemical composition design, microstructure and mechanical properties development during thermomechanical processing, production technology characterisation, potential applications and performance in service. AHSS steels are considered to be the major Advanced High-Strength Steel (AHSS) Definitions Todays AHSS for Automotive. Advanced High-Strength Steels ( AHSS) are complex, sophisticated materials, with carefully selected chemical compositions and multiphase microstructures resulting from precisely controlled heating and cooling processes. Various strengthening mechanisms are employed to achieve a range of strength, ductility, toughness, and fatigue properties.

A major challenge in car design is to meet safety standards that are continually being made tougher, whilst at the same time keeping the weight and cost of the car body to a minimum. With this in mind, SSAB Swedish Steel is continually adding to its range of ultra-high strength steels. The Applications of Advanced High-Strength Steel Advanced high-strength steel refers to a new generation of steel that is revolutionizing the automotive industry with high strength, low weight material. Three generations of advanced high-strength steels for High-strength, low-alloy (HSLA) steels are CMn steels strengthened with the addition of a microalloying amount of titanium, vanadium, or niobium. These steels, with a tensile strength up to 800 MPa (115,000 PSI), still can be press formed (see Figure 2). HSLA was one of the first com-monly used HSS in the automotive industry in the 1990s. These steels
1.1.2 SSABs advanced high strength steel and its benefits for the automotive industry Cars are becoming ever better in terms of safety, comfort and fuel consumption. This trend is driven by increased safety and environmental demands. The utilisation of SSABs advanced high strength steels results in lightweight constructions, improved safetyAdvAnced HigH Strengt H Steel S For tHe Automotive on the market. The term Advanced High Strength Steel (AHSS), is generally used for dual phase steels, complex phase steels, TRip steels and martensitic steels, it means primarly multi phase steels. At SSAB, the high yield strength micro-alloyed steels also belong to AHSS group. Conventional high strength steels are single phase ferritic steels.
