Stainless Steel 321 pipe and Tube Manufacturer & Suppliers
Stainless Steel 321 pipe & Tube is a chromium-nickel steel with improved intergranular corrosion resistance. It is resistant to atmospheric corrosion, sterilizing solutions, many organic chemicals, and a wide variety of inorganic chemicals.
Pipes of Type 321, JIS SUS 321 Pipes, and 321H Stainless Steel Seamless Pipes should be used for applications requiring heating between 800°F and 1650°F, such as aircraft collector rings, expansion joints, exhaust manifolds, and high temperature chemical processing equipment.
We Manufacturer, exporter & supplier of high-quality ASTM A312 TP 321 Stainless Steel Pipes, ASTM A358 TP 321 Stainless Steel EFW Pipes, Welded Pipes, Seamless Pipes. Stainless Steel 321H ERW Pipes are extensively used in aircraft parts, such as exhaust systems, where temperatures exceed 800°F.
The pipes are smoothly processed by our highly experienced experts using basic materials in accordance with market norms. Stainless Steel UNS S32109 Welded 321 Pipe, Suppliers of ASTM A312 TP 321 Stainless Steel Seamless Pipes, 321 Stainless Steel Hollow Pipes, Stainless Steel WERKSTOFF NR. 1.4541 Pipe. Our pipes are manufactured using the latest technology and machines.
Water quench or air cool stainless steel 321H pipes to 1750 °F – 2050 °F (954 °C – 1121 °C). Stainless Steel 321 Seamless Pipes can be stress-relief annealed within the sensitization range of 450 – 800 degrees Celsius without carbide precipitation occurring, preventing intergranular corrosion.
In the annealed condition, our Stainless Steel 321 Round Pipes have slightly less corrosion resistance than Alloy 302 or Alloy 304. Food processing and aerospace applications use these Stainless Steel 321H Square Pipes and ASTM A312 TP321 Stainless Steel Seamless Pipes.
Overall, these Stainless Steel 321H Welded Pipes are an excellent, relatively low-cost choice for many applications. The main difference between stainless steel 321 EFW Pipes and stainless steel 304 and 304L is the titanium addition, which reduces or prevents carbide precipitation during welding.
