The physical properties of stainless steel?
Comparison with carbon steel
1. Density
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.
2. Resistivity
The resistivity increases in order of carbon steel, ferritic type, martensitic type and austenitic type stainless steel.
3, the order of the linear expansion coefficient is similar, Austenitic stainless steel is the highest and carbon steel is the smallest;
4, carbon steel, ferritic and martensitic stainless steel magnetic, Austenitic stainless steel non-magnetic, but its cold work hardening martensitic phase transition will produce magnetic, heat treatment method can be used to eliminate this martensitic structure and restore its non-magnetic.
