Alloy 20 yakozwe muburyo bwihariye bwo kurwanya aside sulfurike. Nikel, chromium, molybdenum hamwe numuringa byose bitanga imbaraga nziza zo kurwanya ruswa. Carbone yagabanijwe hiyongereyeho columbium stabilisation yemerera ibihimbano gusudira gukoreshwa mubidukikije byangirika, mubisanzwe nta kuvura ubushyuhe nyuma ya weld. Kuri nikel 33%, Alloy 20 ifite ubudahangarwa bufatika bwo guhagarika chloride. Iyi mavuta ikunze guhitamo gukemura ibibazo bya SCC, bishobora kubaho hamwe na 316L idafite umwanda.
