Stainless Steel 321 / 321H Coil/Sheet
Stainless Steel 321 and 321H are basic austenitic materials stabilized by the addition of Titanium. They offer high strength, resistance to scaling, and phase stability at temperatures up to 1,650 ℉. 321 is ideal for general high-temperature service, while 321H offers improved creep strength at elevated temperatures. They provide excellent resistance to intergranular corrosion after welding.
