1, chemical properties: resistance to chemical corrosion and electrochemical corrosion in the steel inside is the best, second only to titanium.
2, Physical properties: heat resistance, high temperature, but also ultra-low temperature resistance, low temperature resistance, even.
3, the mechanical properties: according to different types of stainless steel, the mechanical properties are different, martensitic stainless steel with high strength, hardness, corrosion resistance and suitable for the manufacture of both require high strength, high wear resistance of parts, such as turbine shaft, stainless steel knives, stainless steel bearings, austenitic stainless steel good plasticity, strength is not too high, but the corrosion resistance of stainless steel is best suitable for corrosion resistance and mechanical properties need to be very demanding applications, such as chemical plants, fertilizer plant, sulfuric acid, hydrochloric acid timber equipment manufacturers, of course, also be used for submarines and other military industry, mechanical properties of ferritic stainless moderate intensity is not too high, however, resistance to oxidation, suitable for a variety of industrial furnace parts. 4, process performance: the best technological properties of austenitic stainless steel, because good plasticity, workability called various plates, tubes and other profiles, suitable for pressure processing, high hardness martensitic stainless steel due process performance worse.
