Stainless steel elbow Suppliers tell you the physical properties of stainless steel
Compared with carbon steel
The density of carbon steel is slightly higher than that of ferritic and martensitic stainless steels, but slightly lower than that of austenitic stainless steels;
The resistivity is increasing in order of carbon steel, ferrite, martensitic, and austenite stainless steels;
3. The order of 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 magnetic, austenitic stainless steel non-magnetic, but the cold work hardening martensitic transformation will produce magnetic, heat treatment can be used to eliminate the martensite Organize and restore its non-magnetic.
Compared with carbon steel, austenitic stainless steel has the following characteristics:
1) High electrical resistivity, about 5 times that of carbon steel.
2) The large linear expansion coefficient is 40% larger than carbon steel, and as the temperature rises, the value of the linear expansion coefficient increases accordingly.
3) Low thermal conductivity, about 1/3 of carbon steel.
