Physical properties of stainless steel

Physical properties of stainless steel compared with carbon steel
 
1. Density
The density of carbon steel is slightly higher than that of ferrite and martensitic stainless steel, but slightly lower than that of austenitic stainless steel;
 
2. Resistivity
The resistivity increases in the order of carbon steel, ferrite, martensitic and austenitic stainless steel;
 
3. The order of linear expansion coefficient is also similar, austenitic stainless steel is high and carbon steel is the smallest;
 
4. Carbon steel, ferrite and martensitic stainless steel are magnetic, austenitic stainless steel is non-magnetic, but it will produce magnetism when it is cold worked and hardened to form martensitic phase transformation, and heat treatment can be used to eliminate this martensitic structure and restore its non-magnetic nature.
 
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 as the temperature increases, the value of the linear expansion coefficient also increases accordingly.
 
3) Low thermal conductivity, about 1/3 of carbon steel.
