Nickel Alloy Alloy 330 (UNS N08330/W.) 1.4886) is an austenitic alloy with good high-temperature strength and corrosion resistance. It has a solid-solution composition and cannot be hardened by heat treatment. It is rich in nickel and chromium and has good corrosion, oxidation and carbonation resistance. Its oxidation resistance is increased by the increase in silicon content. The strength and oxidation resistance of the alloy at high temperatures make it a useful material for industrial heating furnaces; It is used in silencers, stills, conveyor systems, baskets and boxes, as well as a variety of equipment fixtures.
