Kuphuhliso olubalulekileyo,904L imivalo yentsimbi engenasiciziye zavela njengezinto ezithandwayo kumashishini ashushu kakhulu, ziguqula indlela amacandelo ahlukeneyo aphatha ngayo ubushushu obugqithisileyo.Ngokuxhathisa ubushushu obukhethekileyo kunye nokuqina kwe-corrosion, i-904L yensimbi engenasici izinzile njengendlela yokuya kwizicelo ezibalulekileyo apho amaqondo obushushu aphakamileyo abangela umngeni.
Isibheno se-904L yensimbi engenasici silele ekubunjweni kwayo okuyingqayizivele kunye neempawu.Le alloy iqhayisa umxholo we-chromium ophakamileyo we-23-28%, udibene nekhabhoni ephantsi kunye nomxholo ophezulu we-nickel (19-23%).Ezi mpawu zinegalelo kubuchule bayo obumangalisayo bokugcina imfezeko yesakhiwo kunye nokuxhathisa i-oxidation nakwiimeko ezinokuthi zibangele ukuhla okubonakalayo kwezinye izinto.
