GB/T 20887.3-2010
AbolishedContinuously hot rolled high strength steel sheet and strip for automobile - Part 3: Dual phase steel
汽车用高强度热连轧钢板及钢带 第3部分：双相钢
Application Summary AI generated
This standard specifies the chemical composition, mechanical properties, and dimensional tolerances for continuously hot-rolled dual-phase steel sheets and strips used in automotive manufacturing. It is applied by steel producers and automotive engineers to ensure consistent material performance for structural components like cross members, reinforcement beams, and chassis parts that require high strength and good formability. The standard governs quality control and material selection in the production of lightweight, crash-resistant vehicle bodies.
