Description
321 321H Stainless Steel Seamless Pipe
Pipe Profile
321 stainless steel pipe: high-quality carbon structural steel, alloy structural steel and stainless steel heat-resistant steel seamless steel pipe used for steam boiler pipes mainly used for manufacturing high pressure and above. These boiler pipes are often operated under high temperature and high pressure. The pipe will also oxidize and corrode under the action of high temperature flue gas and water vapor. Therefore, the steel pipe is required to have high durability, high oxidation resistance, good structural stability, and hydraulic pillar pipe.
