Presentation of the Main Types of High Tensile Steels Used in the Automotive Industry and Their Main Applications

Abstract

This paper presents the different types of steels used in the automotive industry and the different parts that form the resistant structure of the vehicle. The types of steels most used in the automotive industry are as follows: HSS (High-Strength Steels); AHSS (Advanced High Strength Steels); TRIP (Transformation Induced plasticity); DP (Double phase); CP (Complex phase); Martensitic start (MS); TWIP (Twinning-Induced Plasticity); FB (Ferrite-Bainitic); PFHT (Post-forming heat treatment); BOR (Boron); BH (Bake Hardening); Interstitial free (IF); Isotropic steel (IS). This work allows having a global point of view of all types of steels used in the automotive industry and their main applications.
