What are the surface finish grades of 304 Stainless Steel Coil?

304 Stainless Steel Coil processing technology refers to the process of cutting, bending, bending, welding and other mechanical processing of stainless steel with the performance of stainless steel to obtain the stainless steel products required for industrial production. In the process of stainless steel processing, a large amount of Tongchuang stainless steel is needed to provide Picture of machine tools, instruments, stainless steel processing equipment. Stainless steel processing equipment is classified into shearing equipment and surface treatment equipment, and shearing equipment is divided into Kaiping equipment and slitting equipment. In addition, from the thickness of stainless steel, there are cold and hot rolling processing equipment. What are the surface finish grades of 304 Stainless Steel Coil?

1. Original surface: the surface treated with heat treatment and pickling after hot rolling. It is generally used for cold-rolled materials, industrial tanks, chemical industrial equipment, etc. The thickness of Tongchuang stainless steel is thicker than 2.0MM-8.0MM.

2. Blunt surface: After cold rolling, it is heat treated and pickled. The material is soft and the surface is silvery white. It is used for deep drawing processing, such as automobile components, water pipes, etc.

3. Matte surface: After cold rolling, heat treatment, pickling, and then finishing rolling to make the surface moderately bright. Because the surface is smooth and easy to re-grind, it makes the surface brighter and has a wide range of uses, such as tableware and building materials. After adopting the surface treatment to improve the mechanical properties, it can meet almost all purposes.

4. Coarse sand: the product is ground with 100-120 grinding belt. It has better gloss and discontinuous rough lines. Used for interior and exterior decoration materials, electrical products and kitchen equipment.

5. Fine sand: the product is ground with a 150-180 grit grinding belt. It has better gloss, discontinuous rough lines, and finer stripes than NO.3. Used in baths, interior and exterior decoration materials of buildings, electrical products, kitchen equipment and food equipment, etc.
