Compared with steel
Slightly higher than the density of steel ferritic and martensitic stainless steel, while slightly lower than austenitic stainless steel;
2, the resistivity
Resistivity by carbon steel, ferritic, martensitic and austenitic stainless steel Sort Ascending;
3, the size of the linear expansion coefficient of the sort similar, austenitic stainless steel and carbon steel up to minimum;
4, carbon steel, ferritic and martensitic stainless steel magnetic, non-magnetic austenitic stainless steel, but it will have to generate a magnetic work hardening, heat treatment method available martensitic transformation to eliminate this martensite organization and restore its non-magnetic.
Compared with austenitic stainless steel, has the following characteristics:
1) high resistivity, carbon steel is about 5 times.
2) a large linear expansion coefficient, 40% larger than that of carbon steel, and as the temperature rises, the value of the linear expansion coefficient is also increased accordingly.
3) low thermal conductivity, about 1/3 of carbon steel.
