Chemical composition: C ≤ 0.08mn ≤ 2p ≤ 0.04s ≤ 0.03Si ≤ 0.75ni: 9 ~ 13 Cr: 17 ~ 20 321 stainless steel seamless pipe: mainly used for manufacturing high-pressure steam boiler pipe and other high-quality carbon structural steel, alloy structural steel and stainless steel heat-resistant steel seamless pipe. These boiler pipes often work under high temperature and pressure, and the pipe will also be oxidized and corroded under the action of high-temperature flue gas and water vapor, Therefore, the steel pipe has high endurance strength, high oxidation resistance, good tissue stability and hydraulic support pipe.
