GB/T 20564.9-2016
ActiveContinuously cold rolled high strength steel sheet and strip for automobile—Part 9: Quenching and partitioning steel
汽车用高强度冷连轧钢板及钢带 第9部分：淬火配分钢
Application Summary AI generated
This standard specifies the chemical composition, mechanical properties, and technical requirements for quenching and partitioning (Q&P) steel sheets and strips used in automobile manufacturing. It is applied in the production of high-strength, lightweight automotive structural and safety components, such as B-pillars and side impact beams, where enhanced formability and crash energy absorption are critical. The standard ensures material consistency for cold-rolled steel supplied to automotive stamping and assembly lines.
