Mu chitukuko chachikulu,904l osapanga dzimbiriAdatulukira monga momwe amakondera m'mafakitale otchedwa mafakitale otentha, magawo osiyanasiyana amagwiritsa ntchito malo otentha kwambiri. Ndi kukana kwapadera kwa kutentha ndi kukhazikika kwa nthaka, 904l osapanga dzimbiri kwadzipangitsa okha kukhala njira yofunsira komwe kutentha kwatenthetsera kumabweretsa zovuta.
Chidwi cha zinthu zopanda phokoso 904l chimakhala pamapangidwe ake apadera ndi katundu wake wapadera. Alloy iyi imadzitamandira chromium yokwezeka ya 23-28%, yophatikizidwa ndi kaboni yotsika komanso yokwera kwambiri ya nickel (19-23%). Izi zimapangitsa kuti pakhale kuperewera kwake pa umphumphu ndi kukaniza maxiyation ngakhale mu zinthu zina zomwe zingayambitse kuchepa kwa zinthu zina.
