Loogu talagalay UNS N08020, Alloy 20 (sidoo kale loo yaqaan "Incoloy 020" ama "Incoloy 20") waa daawaha nikkel-iron-chromium oo lagu daray naxaas iyo molybdenum. Waxay leedahay iska caabbinta daxalka gaarka ah ee sulfuric acid, koloride stress-dillaaca dildilaaca, nitric acid, iyo phosphoric acid. Alloy 20 waxay noqon kartaa mid diyaarsan oo kuleyl ah ama qabow-samaysan oo loo sameeyay valves, qalabka tuubooyinka, flanges, xirayaasha, bambooyinka, taangiyada, iyo sidoo kale qaybaha kulaylka. Heerkulka qaabaynta kulul waa inuu ahaadaa inta u dhaxaysa 1400-2150°F [760-1175°C]. Caadi ahaan, daawaynta kulaylka soo-jiidashada waa in lagu qabtaa heerkulka u dhexeeya 1800-1850°F [982-1010°C]. Alloy 20 waxaa si weyn loogu isticmaalaa soo saarista shidaalka, organic & kiimikooyinka aan organic, processing daawooyinka, iyo warshadaha cuntada.
