ASTM A240 321 stainless steel plate is a stabilized austenitic stainless steel similar to Type 304 ,but with a titanium addition of at least five times the carbon content. 321 stainless steel sheet provides excellent resistance to oxidation and corrosion and possesses good creep strength. A240 321 stainless steel plate is used primarily in applications involving continuous and intermittent service temperatures within the carbide precipitation range of 800 – 1500 °F (427 – 816 °C).
321 stainless steel sheet typical uses include annealing covers, high-temperature tempering equipment, diesel and heavy duty automotive exhaust systems, firewalls, stack liners, boiler casings, welded pressure vessels, jet aircraft components, radiant superheaters, bellows and oil refinery equipment.
