Pachitukuko chachikulu,Mipiringidzo yachitsulo chosapanga dzimbiri ya 904LZakhala zikutchuka kwambiri m'mafakitale otentha kwambiri, zomwe zasintha momwe magawo osiyanasiyana amagwirira ntchito m'malo otentha kwambiri. Chifukwa cha kukana kutentha komanso kupirira dzimbiri, chitsulo chosapanga dzimbiri cha 904L chadzikhazikitsa ngati njira yabwino kwambiri yogwiritsira ntchito pamene kutentha kwambiri kumakhala kovuta.
Chitsulo chosapanga dzimbiri cha 904L chimakopa kwambiri chifukwa cha kapangidwe kake kapadera komanso makhalidwe ake apadera. Chitsulochi chili ndi chromium yochuluka ya 23-28%, kuphatikiza ndi kaboni wochepa komanso nickel yochuluka (19-23%). Zinthu zimenezi zimathandiza kuti chikhale ndi mphamvu yodabwitsa yosunga kapangidwe kake komanso kupewa okosijeni ngakhale m'mikhalidwe yomwe nthawi zambiri ingayambitse kuwonongeka kwakukulu kwa zinthu zina.
