Mu chitukuko chachikulu,904L zitsulo zosapanga dzimbirizakhala zikuyenda bwino m'mafakitale otentha kwambiri, ndikusintha momwe magawo osiyanasiyana amagwirira ntchito ndi kutentha kwambiri. Pokhala ndi mphamvu yolimbana ndi kutentha kwapadera komanso kusasunthika kwa dzimbiri, 904L chitsulo chosapanga dzimbiri chadzipanga kukhala njira yopititsira patsogolo ntchito zovuta zomwe kutentha kwapamwamba kumakhala kovuta.
Kukopa kwa 904L chitsulo chosapanga dzimbiri kwagona mu kapangidwe kake komanso mawonekedwe ake. Aloyiyi ili ndi chromium yokwezeka ya 23-28%, kuphatikiza ndi mpweya wochepa komanso nickel wochuluka (19-23%). Makhalidwewa amathandizira kuti azitha kukhazikika bwino komanso kukana makutidwe ndi okosijeni ngakhale pamikhalidwe yomwe ingawononge kwambiri zida zina.
