GB/T 20564.3-2007
AbolishedContinuously cold rolled high strength steel sheet and strip for automobile - Part 3: High strength interstitial free steel
汽车用高强度冷连轧钢板及钢带 第3部分：高强度无间隙原子钢
Application Summary AI generated
This standard specifies the chemical composition, mechanical properties, and dimensional tolerances for high strength interstitial free (IF) steel sheets and strips produced via continuous cold rolling. It is applied in the automotive industry for manufacturing structural and outer body panels that require superior formability combined with higher strength, such as door panels, fenders, and floor reinforcements. The standard ensures consistent material quality for stamping and forming processes in vehicle production.
