321 Stainless Steel Seamless Pipe
310S stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instruments, etc. When the bending and torsion strength are the same, the weight is lighter, and it is widely used in the manufacture of mechanical parts and engineering structures. Also often used as conventional weapons, barrels, shells, etc.
310s is austenitic chromium-nickel stainless steel with good oxidation resistance and corrosion resistance. Because of the higher percentage of chromium and nickel, 310s has much better creep strength, can work continuously at high temperatures, and has good high temperature resistance. sex.
It has good oxidation resistance, corrosion resistance, acid and salt resistance, and high temperature resistance. The high temperature resistant steel pipe is specially used for manufacturing electric furnace tubes. After the carbon content of austenitic stainless steel is increased, the strength is improved due to its solid solution strengthening effect. The chemical composition of austenitic stainless steel is based on chromium and nickel with elements such as molybdenum, tungsten, niobium and titanium. Because its structure is a face-centered cubic structure, it has high strength and creep strength at high temperatures.
