Compared with carbon steel

1, density

Carbon steel density slightly higher than the ferrite and martensitic stainless steel, and slightly lower than the austenitic stainless steel;

2, resistivity

Resistivity is increased by carbon steel, ferrite, martensitic and austenitic stainless steels;

3, the linear expansion coefficient of the size 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 non-magnetic, but the cold work hardening martensitic transformation will produce magnetic, heat treatment can be used to eliminate this martensite Organization and restore its non-magnetic.

Austenitic stainless steel compared with carbon steel, has the following characteristics:

1) high resistivity, about 5 times the carbon steel.

2) Large linear expansion coefficient, 40% larger than carbon steel, and with the temperature rise, the coefficient of linear expansion coefficient is also increased accordingly.

3) low thermal conductivity, about 1/3 of carbon steel.
