E khethiloe e le UNS N08020, Alloy 20 (eo hape e tsejoang e le "Incoloy 020" kapa "Incoloy 20") ke motsoako oa nickel-iron-chromium o nang le litlatsetso tsa koporo le molybdenum. E na le khanyetso e ikhethang ea corrosion ho sulfuric acid, choloride stress-corrosion cracking, nitric acid, le phosphoric acid. Alloy 20 e ka ba e chesang habonolo kapa e batang ho li-valve, lisebelisoa tsa liphaephe, li-flanges, li-fasteners, lipompo, litanka, hammoho le likarolo tsa mocheso. Mocheso o chesang oa ho bopa e lokela ho ba ka har'a 1400-2150°F [760-1175°C]. Hangata, phekolo ea mocheso ea ho tsuba e lokela ho etsoa ka mocheso oa 1800-1850 ° F [982-1010 ° C]. Alloy 20 e sebelisoa haholo bakeng sa tlhahiso ea peterole, organic & inorganic chemicals, pheko ea meriana le indasteri ea lijo.
