Stainless Steel Flat Bar Production Process
The production process of stainless steel flat steel mainly includes the following steps:
Smelting: Melt the stainless steel raw materials at high temperature, remove impurities, and add necessary alloy elements.
Casting: Pour the molten stainless steel liquid into a mold and cool it into a stainless steel ingot.
Hot rolling or cold drawing: The stainless steel ingot is processed into a rectangular cross-section by hot rolling or cold drawing.
Annealing: Annealing eliminates internal stress and improves the ductility and toughness of the material.
Surface treatment: Surface polishing, pickling and other treatments are performed to improve surface finish and corrosion resistance.
