Classification of stainless steel
1. According to the chemical composition, it can be divided into: chromium stainless steel, chromium-nickel stainless steel, chromium-manganese stainless steel, chromium-nickel-molybdenum stainless steel, ultra-low carbon stainless steel, high molybdenum stainless steel, high-purity stainless steel, etc.
2. According to the metallographic structure, it can be divided into: martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, austenitic-ferritic stainless steel, etc.
3. 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.
4. 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.
