Kuphuhliso olubalulekileyo,904L imivalo yentsimbi engenasiciziye zavela njengezona zinto zithandwayo 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 obuchukumisayo bokugcina imfezeko yesakhiwo kunye nokuxhathisa i-oxidation nakwiimeko ezinokuthi zibangele ukuwohloka okukhulu kwezinye izinto.
