333 Sheet and plate - Heat and Corrosion Resistant Rolled Alloy

RA333 l Heat Resistant Alloys l Product Line

RA333 is a high chromium nickel base superalloy with outstanding resistance to high temperature oxidation, carburization, and thermal shock. In a gas fired application, RA333 alloy has been heated as high as the incipient melting point with no significant metal loss from oxidation. RA333 is one of the few materials that can withstand corrosive conditions ranging from aqueous to white heat. The alloy has been used for dampers and refractory anchors in 13% SO2/SO3 at 1800°F, and for refinery flare tips. Upon shut-down, RA333 resists attack by sulfuric and polythionic acids formed below the dew point. RA333 has exceptional resistance to molten glass and has replaced platinum spinnerets in the manufacture of fiberglass.
