What is 321 stainless steel tube / 321h stainless steel pipe?
321 stainless steel tube / 321h stainless steel pipe are stabilized austenitic stainless steel alloys that contain titanium, which enhances their corrosion resistance and ability to withstand high temperatures. They offer good mechanical properties in elevated temperatures, formability, and weldability, making them ideal for industrial applications such as heat exchangers, boiler tubes, high-pressure vessels, process lines, and condenser systems.
What are the advantages of SS 321/321H Pipes & Tubes?
321h stainless steel pipe and 321 stainless steel tubing offers excellent resistance to oxidation and scaling at high temperatures, good toughness at low temperatures, and good creep strength up to 900°C. They also have low thermal expansion and resistance to chloride stress corrosion cracking, making them ideal for applications with temperatures between 850°C and 1100°C.
What are the applications of Stainless Steel 321 / Stainless Steel321H Pipes & Tubes?
321h stainless steel pipe and 321 stainless steel tubing are widely used in various industries such as petrochemical, chemical, power generation, and oil and gas. They are also used in equipment like tanks, pumps, and valves. Other applications include automotive exhaust systems, textile machinery components, and food processing equipment. In addition to their excellent corrosion resistance properties, 321/321H stainless steel pipes and tubes are a cost-effective alternative to copper-nickel alloys for many applications.
