Physical properties of Stainless Steel Patch fittings
Comparison of stainless steel Patch fittings with carbon steel Patch fittings
Carbon steel Patch fittings have a slightly higher density than ferritic and martensitic stainless steel patch fittings, and are slightly lower than austenitic stainless steels;
The resistivity is increasing in order of carbon steel, ferrite, martensitic, and austenitic stainless steels;
3, the order of the linear expansion coefficient is also similar, austenitic stainless steel Patch fittings highest, and carbon steel minimum;
4, carbon steel, ferritic and martensitic stainless steel Patch fittings magnetic, austenitic stainless steel non-magnetic, but the cold work hardening will produce martensitic phase transformation will occur, heat treatment can be used to eliminate this horse The spongy tissue recovers its non-magnetic properties.
Austenitic stainless steel Patch fittings have the following features compared to carbon steel:
1) High electrical resistivity, about 5 times that of carbon steel.
2) The large linear expansion coefficient is 40% larger than that of 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.
