Compare with carbon steel
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;
Resistivity by carbon steel, ferritic, martensitic and austenitic stainless steel in increasing order;
3, the linear expansion coefficient of the size of the order is similar to the highest austenitic stainless steel and carbon steel minimum;
4, carbon steel, ferritic and martensitic stainless steel magnetic, austenitic stainless steel non-magnetic, but the cold work hardening martensitic transformation will produce magnetic, heat treatment can be used to eliminate this martensite Tissue to restore its non-magnetic.
Austenitic stainless steel and carbon steel compared with the following characteristics:
1) high resistivity, about 5 times the carbon steel.
2) Large linear expansion coefficient, 40% larger than carbon steel, and as the temperature increases, the linear expansion coefficient values also increased accordingly.
3) Low thermal conductivity, about 1/3 of carbon steel.《FROM TERADA》
