Comparison between stainless steel and carbon steel.
Email Details
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 according to the order of carbon steel, Ferritic, martensitic and austenitic stainless steel.
3. The order of linear expansion coefficient is similar, austenitic stainless steel is the highest and carbon steel is the smallest.
4. Carbon steel, Ferritic and martensitic stainless steels are magnetic, while austenitic stainless steels are not magnetic, but their cold work hardening results in martensitic transformation. Heat treatment can be used to eliminate this martensitic structure and restore its non-magnetism.
