Entuthukweni ebalulekile,904L imigoqo yensimbi engagqwalizivele njengezisetshenziswa ezithandwayo ezimbonini ezisezingeni eliphezulu, ziguqule indlela imikhakha eyahlukene ephatha ngayo izindawo zokushisa ezidlulele. Ngokumelana kwayo nokushisa okukhethekile kanye nokumelana nokugqwala, insimbi engagqwali engu-904L izitholele yona njengendlela yokuya kuyo yezinhlelo zokusebenza ezibucayi lapho amazinga okushisa aphakeme ebeka inselele.
Isikhalo se-904L yensimbi engagqwali silele ekwakhiweni kwayo okuyingqayizivele kanye nezakhiwo. Le alloy inokuqukethwe okuphezulu kwe-chromium okungu-23-28%, kuhlanganiswe nekhabhoni ephansi kanye nokuqukethwe kwe-nickel ephezulu (19-23%). Lezi zibaluli zifaka isandla ekhonweni layo elimangalisayo lokugcina ubuqotho besakhiwo nokumelana ne-oxidation ngisho nasezimeni ezingabangela ukuwohloka okukhulu kwezinye izinto.
