321 Stainless Steel Sheet
Strength and toughness at sub-zero temperatures.
321 stainless steel sheet is an austenitic material that is stabilised with titanium.
As the primary advantage, 321 stainless steel sheets offer excellent resistance to intergranular corrosion at temperatures in the chromium carbide precipitation range from 427 to 816°C (800 to 1500°F). The titanium-stabilised product benefits from reduced carbide precipitation during welding, which improves the alloy's suitability for use in elevated temperatures. 321 stainless is easily welded and formed and is resistant to oxidating environments. The alloy maintains strength and toughness in sub-zero temperatures.
Commercial Applications
Typical applications include heat exchangers, petrochemical processing equipment, pressure vessels, boilers and aerospace engine components. The alloy offers improved creep and stress rupture properties compared to 304/304L in the annealed condition.
Stock Availability
