Stainless steel coil is a steel product with corrosion resistance, primarily alloyed with chromium and nickel. Common types include austenitic, ferritic, martensitic, and duplex stainless steel cold-rolled and hot-rolled coils. It is mainly produced through cold or hot rolling processes, featuring various surface finishes such as bright, matte, and semi-gloss. The thickness ranges from 0.1 to 15mm, with widths spanning 500 to 2000mm (including edge burrs). Its corrosion resistance stems from the chromium passivation film formed on the surface, while mechanical properties are ensured through annealing, solution treatment, and other processes. It complies with domestic and international standards such as GB, ASTM, and JIS, and is widely used in chemical, food, construction, and mechanical manufacturing industries.
