Kwinkqubela ebalulekileyo,Iibha zentsimbi engagqwaliyo ezingama-904Lziye zavela njengezinto ezithandwa kakhulu kumashishini ashushu kakhulu, nto leyo eguqula indlela amacandelo ahlukeneyo aphatha ngayo iimeko zobushushu obugqithisileyo. Ngenxa yokumelana kwayo nobushushu obugqithisileyo kunye nokumelana nokugqwala, intsimbi engagqwaliyo ye-904L izibonakalise njengokhetho olufanelekileyo kwizicelo ezibalulekileyo apho amaqondo obushushu aphezulu eba ngumceli mngeni.
Ubuhle bentsimbi engagqwaliyo ye-904L buxhomekeke kulwakhiwo lwayo olukhethekileyo kunye neempawu zayo. Le alloy inomxholo ophezulu we-chromium we-23-28%, kunye nekhabhoni ephantsi kunye nomxholo ophezulu we-nickel (19-23%). Ezi mpawu zinegalelo kubuchule bayo obumangalisayo bokugcina ukuqina kwesakhiwo kunye nokumelana ne-oxidation nakwiimeko ezinokubangela ukonakala okukhulu kwezinye izinto.
