JIS G3131 SPHC steel coil quality control standard

JIS G3131 SPHC steel coil quality control standard

JIS G3131 SPHC steel coil quality control standards usually include the following aspects:

1. Chemical composition control: for carbon content, manganese content, silicon content, sulfur content, phosphorus content and other elements, it is required to meet the chemical composition within a specific range.

2. Mechanical properties control: including yield strength, tensile strength, elongation and other mechanical properties parameters, which are required to meet the values specified in the standard.

3. Size and shape control: Check and control size and shape characteristics such as thickness, width, length and flatness of JIS G3131 SPHC steel coil.

4. Surface quality control: Check the oxidation, scratches, spots, rust and other conditions on the surface of JIS G3131 SPHC steel coil to ensure that the surface quality meets the standard requirements.

5. Coating or treatment control: If there are coating or special treatment requirements, it is necessary to test the adhesion and uniformity of the coating.

6. Packaging and marking requirements: The standard specifies the packaging method, transportation requirements and necessary marking content of JIS G3131 SPHC steel coil.

These quality control standards ensure that the JIS G3131 SPHC steel coil produced meet the relevant requirements, ensure that their quality is stable and reliable, suitable for a variety of applications, and help meet the needs and expectations of customers.
