1, the density
Carbon steel density slightly higher than the ferrite and martensitic stainless steel, and slightly lower than the austenitic stainless steel;
2, the resistivity
Resistivity according to the carbon steel, ferritic, martensitic and austenitic stainless steel sort ascending;
3, the size of the linear expansion coefficient of the sort is also similar to the highest austenitic stainless steel and carbon steel minimum;
4, carbon steel, ferritic and martensitic stainless steel magnetic, austenitic stainless steel is not magnetic, but its cold work hardening to produce martensitic transformation will produce magnetic, heat treatment can be used to eliminate this martensite Tissue and restore its non-magnetic.
