321 stainless steel seamless pipe: it is mainly used to manufacture high-pressure steam boiler pipes and other high-quality carbon structural steel, alloy structural steel and stainless steel heat-resistant steel seamless pipes. These boiler pipes usually work under high temperature and high pressure. The pipes 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 and good performance Good tissue stability, hydraulic support tube.
