The main material components of stainless steel tube 631 are chromium, nickel, molybdenum, and other elements. Among them, the chromium content is relatively high, up to 17-19%, which makes stainless steel pipe 631 have excellent corrosion resistance. In addition, the content of nickel accounts for 8-10%, while the content of molybdenum accounts for 1.75-2.50%. The addition of these elements can improve the mechanical and heat resistance properties of stainless steel pipes.
The production process of stainless steel tube 631 generally adopts hot rolling or cold drawing processes. In the hot rolling process, the billet is preheated first, then rolled through a rolling mill, and finally the finished product is obtained through process steps such as cooling, shaping, and finishing. The cold drawing process includes multiple steps such as drawing, pickling, and annealing to ensure the mechanical properties and corrosion resistance of the material.
