What are the physical property comparisons between stainless steel parts and carbon steel? Stainless steel is the abbreviation of stainless acid-resistant steel. It is a type of steel that is resistant to weak corrosive media such as air, steam and water or has the property of not rusting.

　　Stainless steel parts
　　1Density
　　The density of carbon steel is slightly higher than that of ferritic and martensitic stainless steel, but slightly lower than that of austenitic stainless steel.

　　2Resistivity
　　The resistivity increases in the order of carbon steel, ferritic type, martensitic type and austenitic type stainless steel.

　　3The ranking of the coefficient of linear expansion is similar, with austenitic stainless steel having the highest coefficient and carbon steel the smallest.

　　4Carbon steel, ferritic and martensitic stainless steels are magnetic, while austenitic stainless steels are non-magnetic. However, when they undergo cold work hardening to form a martensitic transformation, they will become magnetic. This martensitic structure can be eliminated by heat treatment methods to restore their non-magnetism.
