JIS G3141-2005 is the specification of cold rolled steel in the Japanese industrial standard, and SPCC is a cold rolled steel defined in the specification, the following is the details of its specifications and characteristics:
Specification:
1. Classification: SPCC cold rolled steel is a low carbon cold rolled steel of commercial quality.
2. Size requirements: Specifies the thickness, width and length range of SPCC cold rolled steel plates, strips and coils. For example, the thickness range of sheets is usually 0.15mm to 3.2mm.
3. Surface treatment: grease coating, galvanizing, chemical treatment and other surface treatment can be carried out.
Features:
1. Mechanical properties: SPCC cold rolled steel has good ductility and formability, suitable for cold working and forming operations.
2. Chemical composition: The carbon content of SPCC cold rolled steel is low, generally not more than 0.15%. In addition, limits for other elements, such as sulphur, phosphorus and tin, are specified.
3. Surface quality: The surface of the cold-rolled steel plate should be smooth and smooth, without obvious scratches, wrinkles and rust and other defects.
4. Resistivity: The resistivity of SPCC cold rolled steel should meet the specifications to ensure that its electrical properties meet the relevant application requirements.
5. Application: SPCC cold rolled steel is widely used in automotive parts, electrical appliances, furniture, building materials and other fields, such as body shell, brake system components, home appliance shell and so on.
In general, JIS G3141-2005 SPCC cold rolled steel complies with code requirements, has good mechanical properties and surface quality, is suitable for a variety of applications, and provides a commercial quality low carbon cold rolled steel option.
