Comparison with carbon steel

1, the density of

The density of carbon steel is slightly higher than that of ferrite and Martensite stainless steel, but slightly lower than that of austenite stainless steel.

2. Resistivity

The resistivity increases according to the order of carbon steel, ferrite type, Martensite type and austenite type stainless steel;

3, the order of linear expansion coefficient is similar, austenitic stainless steel is the highest and carbon steel is the lowest;

4, carbon steel, ferritic shape and Martensitic stainless steel is magnetic, austenitic stainless steel is not magnetic, but its cold work hardening generated martensitic phase transformation will produce magnetic, available heat treatment method to eliminate the martensitic structure and restore its non-magnetic.

Compared with carbon steel, austenitic stainless steel has the following characteristics:

1) High resistivity, about 5 times that of carbon steel.

2) large linear expansion coefficient, 40% larger than carbon steel, and with the increase of temperature, the value of linear expansion coefficient also increases accordingly.

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