Stainless Steel Square Bar Production Process
The production process of stainless steel square steel mainly includes the following steps:
1. Melting: Melt the stainless steel raw materials at high temperature, remove impurities, and add necessary alloy elements.
2. Casting: Pour the molten stainless steel liquid into the mold and cool it into a stainless steel ingot.
3. Hot rolling or cold drawing: The stainless steel ingot is processed into a square section by hot rolling or cold drawing.
4. Annealing: Eliminate internal stress through annealing and improve the ductility and toughness of the material.
5. Surface treatment: Perform surface polishing, pickling and other treatments to improve surface finish and corrosion resistance.
