Questions about seamless stainless steel pipe heating

Seamless stainless steel pipe has strong corrosion resistance, is easy to process into various shapes of steel, has good welding performance, and has no tendency to be cold and brittle, so it is widely used. The stainless steel seamless pipe does not undergo phase change, and heat treatment is heated to a high temperature to make it solidify during processing.

Seamless stainless steel pipe has low thermal conductivity, and it can increase thermal conductivity after being heated to high temperature. The heating of stainless steel seamless pipe is based on the carbide solid solution rate. Carbide in 304 stainless steel needs 3 seconds at 1065 degrees Celsius, 1.5 seconds at 1176 degrees Celsius, and 10 seconds at 1000 degrees Celsius. From this point of view, the heating temperature of the stainless steel seamless pipe is as high as possible. But the higher the heating temperature, other defects appear at the same time. will result in a decrease in tensile strength.
