Ikhethwe njenge-UNS N08020, i-Alloy 20 (eyaziwa nangokuthi "i-Incoloy 020" okanye "i-Incoloy 20") i-alloy ye-nickel-iron-chromium enezongezo zobhedu kunye ne-molybdenum. Inokumelana ne-corrosion ekhethekileyo kwi-asidi yesulfuric, i-choloride yoxinzelelo-i-corrosion cracking, i-nitric acid, kunye ne-phosphoric acid. I-alloy 20 iyakwazi ukutshisa ngokukhawuleza okanye ibanda-ifakwe kwiivalve, izifakelo zemibhobho, iiflanges, i-fasteners, iimpompo, iitanki, kunye nezixhobo zokutshintsha ubushushu. Ubushushu bokwenza iqondo lokushisa kufuneka bube kuluhlu lwe-1400-2150°F [760-1175°C]. Ngokuqhelekileyo, unyango olushushu lwe-annealing kufuneka luqhutywe kwiqondo lokushisa le-1800-1850 ° F [982-1010 ° C]. I-alloy 20 isetyenziselwa kakhulu ukuveliswa kwepetroli, i-organic & inorganic chemicals, ukusetyenzwa kwamayeza, kunye neshishini lokutya.
