Physical properties of stainless steel

Comparison 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

Resistivity is in ascending order of carbon steel, ferritic, martensitic and austenitic stainless steels;

3, the size of the linear expansion coefficient is also similar, austenitic stainless steel is the highest and carbon steel is the smallest;

4, carbon steel, ferritic and martensitic stainless steel is magnetic, austenitic stainless steel is non-magnetic, but its cold work hardening to generate martensitic transformation will produce magnetic, can be heat treatment method to eliminate this martensitic tissue and restore its non-magnetic.
