GNEE is a manufacturer, supplier and exporter of A249 TP321 Stainless Steel Pipe and pipes made of high quality raw materials. GNEE products are designed in accordance with major international standards and sold in many countries around the world.
A249 TP 321 High Temperature Tube is a titanium stabilized austenitic stainless steel. The main components include chromium, nickel and a small amount of titanium. The addition of nickel enhances the high temperature resistance of the material, allowing it to maintain high strength and toughness in high temperature environments. Therefore, A249 TP 321 High Temperature Stainless Steel Tube has excellent resistance to intergranular oxidation after exposure to chromium carbide precipitation temperatures in the range of 800-1500°F.
A249 TP321 Cold Drawn Stainless Steel Tube is used in high pressure equipment such as boilers, superheaters, heat exchangers and condensers due to its ability to maintain strength at high temperatures and resist high pressure and corrosion.
