GB/T 5213-2001 is the national standard of China, which specifies the size, shape, weight, technical requirements, test methods, inspection rules, packaging, marking and quality certificate of cold rolled steel sheet and steel strip for deep stamping. This standard is especially suitable for high quality cold rolled low carbon and no gap atomic steel plates and strips for deep stamping deformation complex parts such as the automotive industry.
Chemical composition of GB/T 5213-2001 steel
Under the GB/T 5213-2001 standard, there are clear requirements for the chemical composition of cold rolled steel sheets and steel strips for deep stamping, among which:
Carbon (C) : Maximum content 0.15%
Manganese (Mn) : Maximum content 0.60%
Phosphorus (P) : Maximum content 0.100%
Sulfur (S) : Maximum content 0.050%
Silicon (Si) : Maximum content 0.050%
Aluminum (Al) : Maximum content 0.015%
GB/T 5213-2001 steel characteristics
Mechanical properties: GB/T 5213-2001 standard specifies the tensile strength, yield point, elongation and other mechanical properties of cold rolled steel sheet and steel strip for deep stamping, ensuring the high quality and reliability of the product.
Surface quality: The standard requires that the surface of the steel plate should be smooth and clean, without cracks, scratches and rust, to ensure the appearance quality of the product.
Dimensional accuracy: The standard clearly specifies the allowable range of thickness, width and length deviation of the steel plate, ensuring that the product can meet the user's requirements.
GB/T 5213-2001 standard for deep stamping cold-rolled steel sheet and steel strip is mainly used in the automotive industry and other fields, the manufacture of deep stamping deformation complex parts, such as body, chassis and other parts. In addition, because the steel has good stamping performance and weldability, it is also widely used in household appliances, machinery manufacturing and other industries.
