Yagenwe nka UNS N08020, Alloy 20 (izwi kandi nka “Incoloy 020” cyangwa “Incoloy 20”) ni nikel-fer-chromium ivanze hiyongereyeho umuringa na molybdenum. Ifite ruswa idasanzwe yo kurwanya aside sulfurike, choloride ihangayikishije-ruswa, acide nitric, na aside fosifori. Alloy 20 irashobora kuba byoroshye gushyuha cyangwa gukonjeshwa kubibaya, ibyuma bifata imiyoboro, flanges, ibifunga, pompe, tanks, hamwe nibice bihindura ubushyuhe. Ubushyuhe bwo gushyuha bugomba kuba buri hagati ya 1400-2150 ° F [760-1175 ° C]. Ubusanzwe, kuvura ubushyuhe bwa annealing bigomba gukorwa ku bushyuhe bwa 1800-1850 ° F [982-1010 ° C]. Alloy 20 ikoreshwa cyane mugukora lisansi, imiti kama & organic organique, gutunganya imiti, ninganda zibiribwa.
