GB/T 20564.2-2006
AbolishedContinuously cold rolled high strength steel sheet and strip for automobile - Part 2: Dual phase steel
汽车用高强度冷连轧钢板及钢带 第2部分:双相钢
Application Summary AI generated
This standard specifies the chemical composition, mechanical properties, and dimensional tolerances for dual-phase (DP) steel sheets and strips produced via continuous cold rolling. It is applied in the automotive industry for manufacturing structural and safety components, such as cross members, pillars, and reinforcement parts, where high strength and good formability are required for crash energy absorption. The standard ensures material consistency for stamping and welding processes in vehicle body-in-white production.
