High strength sheet metal stamping technology is the future development direction

High strength steel is used more and more in automobiles because of its excellent properties in the aspects of the ratio of buckling strength, the characteristic of strain hardening, the ability of strain distribution and the ability of collision absorbing energy.At present, high strength steel used in automobile stamping parts mainly includes BH steel, DP steel, TRIP steel, etc.International super light body project (ULSAB) is expected to launch in 2010 advanced concept model (ULSAB - AVC) 97% of the materials for high strength steel, advanced high strength steel plate in the proportion of the vehicle material will be more than 60%, of which the proportion of dual phase steel will account for 74% of vehicle plate.
