Introduction to the physical properties of pipe elbows
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 increased by the carbon steel, ferrite, martensitic, and austenitic 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.
Looking forward to your inquiry for this mitre elbow pipe elbow.
