We offer these SS 321 Pipes and Tubes in international quality standard to our customers. These Stainless Steel 321 Tubes (UNS S32100) are used in Aircraft exhaust manifolds, Expansion joints, Bellows, Furnace parts, Heating element tubing, Heat Exchangers, Woven or welded screens for high temperature mineral processing, Spiral Welded tube for burner pipes and flues. SS 321 Seamless Pipes is the choice for applications in the temperature range of up to about 900 Degree C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion. SS 321 Welded Pipes is generally considered to have comparable weldability to SS 304 and SS 304L with the main difference being the titanium addition which reduces or prevents carbide precipitation during welding. We are also offers these products in custom-made sizes and shapes to esteemed clients.
