According to the main chemical composition, it can be divided into chromium stainless steel, chromium-nickel stainless steel, chromium-manganese-nitrogen stainless steel, chromium-nickel-molybdenum stainless steel, ultra-low carbon stainless steel, high-molybdenum stainless steel, high-purity stainless steel, etc.;
According to the performance characteristics and uses of steel, such as nitric acid-resistant (nitric acid grade) stainless steel, sulfuric acid-resistant stainless steel, pitting-resistant stainless steel, stress-resistant stainless steel, high-strength stainless steel, etc.
According to the functional characteristics of steel, such as low-temperature stainless steel, non-magnetic stainless steel, free-cutting stainless steel, superplastic stainless steel, etc.
American Classification Method: Features and uses of 200, 300, 400 series products. (201, 202, 300, 301 materials are similar, mostly used for decorative materials).
