Chemical properties: Chemical and electrochemical corrosion resistance is the best in steel, second only to titanium.

Physical properties: heat resistance, high temperature resistance, low temperature resistance and even ultra-low temperature resistance.

Mechanical properties: Mechanical properties vary according to the type of stainless steel. Martensitic stainless steel has high strength and hardness and is suitable for manufacturing parts that are both corrosion resistant and require high strength and high wear resistance, such as turbine shafts, stainless steel tools, and stainless steel bearings. Austenitic stainless steel has good plasticity. It is not very high in strength, but its corrosion resistance is the best in stainless steel. It can be used as equipment materials in occasions that require very good corrosion resistance and low mechanical properties, such as chemical plants, fertilizer plants, sulfuric acid, hydrochloric acid manufacturers. Of course, it can also be used in the military industry such as submarines. Ferritic stainless steel has moderate mechanical properties and is not very strong in strength yet it is resistant to oxidation and is suitable for various industrial furnace parts.
