GB/T 20564.1-2007
AbolishedContinuously cold rolled high strength steel sheet and strip for automobile - Part 1：Bake hardening steel
汽车用高强度冷连轧钢板及钢带 第1部分：烘烤硬化钢
Application Summary AI generated
This standard specifies the technical requirements, test methods, and inspection rules for continuously cold-rolled bake hardening (BH) steel sheets and strips used in automobile manufacturing. It is applied in the production of automotive body panels and structural components where the material gains additional strength during the paint-baking process. The standard ensures consistent mechanical properties and formability for parts requiring dent resistance and lightweight design.
