The body parts of cold-rolled automobile steel are roughly divided into panel parts, structural parts, walking parts and reinforcing parts. Different parts correspond to different application requirements and have different performance. Panel components require that the plate has good formability, strength, elongation, sag resistance, corrosion resistance, etc. The structural parts require the plates to have good formability, strength, impact energy absorption capacity, fatigue durability, corrosion resistance and weldability. Walking parts are required to have good formability, rigidity, fatigue durability, corrosion resistance and weldability; The excellent collision energy absorption capacity and weldability are especially important for the reinforcing parts.
