Seamless stainless steel pipes have strong corrosion resistance, are easy to process into various shapes of steel, have good welding performance, and have no tendency to cold brittleness, so they are widely used. The stainless steel seamless tube does not undergo phase transformation, and the heat treatment is heated to a high temperature to solidify it during processing.
Seamless stainless steel tubes have low thermal conductivity and can increase thermal conductivity when heated to high temperatures. The heating of stainless steel seamless pipe is based on the solid solution rate of carbide. Carbides in 304 stainless steel take 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.
