cold forming and molding of stainless steel and its treatmentSome molding processes allow for slippery contact between metals. Local high pressure during molding can protect the passivation film that protects the stainless steel and may cause the cold surface of the unprotected stainless steel surface to weld to the surface of the tool.scrap steel exports,scrap steel pricesThe solder joints in the next step in the slide break, has been contaminated with debris tools, the mold surface will be in the stainless steel surface caused serious scratches. This requires the need to ensure that the forming equipment intact, while requiring skilled workers operating procedures, careful operation, to avoid the phenomenon of sponge material.stainless steel sheet exportsStainless steel has a high strength, in which austenitic stainless steel also has a significant cold hardening characteristics, if the cold forming process, the deformation is too large, will lead to the workpiece fracture, serious and even damage to molds and machinery and equipment. Therefore, in the production process, the hardness of the workpiece should be detected, and maintain a reasonable amount of deformation, in ensuring the quality of products to meet the needs of production efficiency.good quality stainless steel plateStainless steel workpiece in the cold forming, the surface passivation film will be damaged, but also adhesion stamping oil, mold and other metal debris, etc., is likely to cause corrosion. In order to make the workpiece after the workpiece has a good stainless steel and finish, but also to clean it to the oil and passivation treatment, conditional can also use plastic film to protect the surface of the workpiece.304 stainless steel sheet&coil
