AbolishedContinuously hot rolled high strength steel sheet and strip for automobile - Part 1: High yield strength steel for cold forming
汽车用高强度热连轧钢板及钢带 第1部分：冷成形用高屈服强度钢
Application Summary AI generated
This standard specifies the chemical composition, mechanical properties, and dimensional tolerances for continuously hot-rolled high-strength steel sheets and strips with high yield strength intended for cold forming in automobile manufacturing. It is applied by automotive OEMs and steel suppliers to ensure material consistency for structural components like chassis frames, cross members, and reinforcement parts that require both high strength and formability. The standard governs material selection and quality control in the production and procurement of steel for vehicle body and safety-related parts.
