AbolishedContinuously cold rolled high strength steel sheet and strip for automobile - Part 7: Martensitic steels
汽车用高强度冷连轧钢板及钢带 第7部分：马氏体钢
Application Summary AI generated
This standard specifies the technical conditions for continuously cold-rolled martensitic steel sheets and strips used in automotive manufacturing. It defines mechanical properties, dimensional tolerances, and testing methods for these ultra-high-strength steels, which are applied in structural and safety components such as door impact beams, bumper reinforcements, and chassis parts. The standard ensures material consistency for stamping and welding processes in automotive production lines.
