High-strength steel plate stamping technology is the future development direction




   Automotive mold high-strength steel has excellent characteristics in terms of yield ratio, strain hardening characteristics, strain distribution ability and impact energy absorption, and its use in automobiles is increasing. At present, the high-strength steels used in automotive stampings mainly include paint hardening steel (BH steel), dual-phase steel (DP steel), and phase transformation induced plasticity steel (TRIP steel). It is estimated that 97% of the materials of the advanced concept vehicle (ULSAB-AVC) launched in 2010 will be high-strength steel, and the proportion of advanced high-strength steel in the vehicle materials will exceed 60%. The proportion of duplex steel will account for 74% of automotive steel plates.




Nowadays, the widely used mild steel series mainly based on IF steel will be replaced by high-strength steel plate series, and high-strength low-alloy steel will be replaced by dual-phase steel and ultra-high-strength steel plate. At present, the application of high-strength steel plates for domestic auto parts is mostly limited to structural parts and beams, and the tensile strength of the materials used is mostly below 500MPa. Therefore, quickly mastering the stamping technology of high-strength steel plates is an important problem that needs to be solved urgently in my country's automobile mold industry.
