321 Stainless Steel Tube
Carbide precipitation resistant at high temperatures.
Our 321 stainless steel tubes are stabilised with titanium and offer resistance to intergranular corrosion.
321 stainless steel is similar to Type 304 but with greater levels of carbon and titanium. Including titanium makes the alloy more resistant to carbide precipitation at elevated temperatures. 321 is often referred to as a heat-resistant grade because good corrosion resistance and strength characteristics are maintained even at high-temperature levels. As 321 is austenitic, toughness and overall strength are maintained at cryogenic temperatures. The material also offers good weldability with superior creep and stress rupture capabilities compared to Type 304 and 304L.
Commercial Applications
The alloy is used in demanding applications such as high-temperature environments and includes exhaust stacks, expansion joints, engine manifolds and oil refinery equipment.
