Stainless Steel 321/321H Sheet/Plate
Stainless Steel 321 is a titanium-stabilized austenitic stainless steel grade designed for service in the temperature range of 1000-1600°F. It offers excellent resistance to intergranular corrosion and stress corrosion cracking due to the addition of titanium, which suppresses chromium carbide precipitation at grain boundaries. It possesses good low-temperature toughness, is non-magnetic in the annealed condition, and exhibits high resistance to creep and stress rupture. Commonly used in oil refineries, chemical plants, and high-temperature exhaust systems.
