904 Chitsulo Chopanda Chitsulondi mtundu wa zitsulo zosapanga dzimbiri zokhala ndi zosapanga zotsika kwambiri za kaboni komanso zokongola kwambiri zopangidwa m'malo mwa malo okhala ndi ziphuphu. Ili ndi kukana kwamphamvu kuposa 316l ndi 317l, ndikuganizira kuchuluka kwa mtengo ndi magwiridwe antchito. Kufunika kwa ndalama. Chifukwa chowonjezera mkuwa 1.5%, umakhala ndi vuto lalikulu kuwongolera motsutsana ndi ma sulfuric acid ndi phosphoric acid. Ilinso ndi kukana kwabwino kwambiri popewa kupsinjika, kuthirira ndi crevice kuturumo kokhazikika ndi ma ions, ndipo amakhala ndi kukana bwino kuphatikizira. Ku Slulfuric acid a acid osiyanasiyana a 0-98%, kutentha kwa ntchito ya 904l yachitsulo kumatha kukhala okwera madigiri 40.
M'maci a asidi wangwiro mu 0-85%, kukana kwake kutukula ndikwabwino kwambiri. Mu mafakitale a phosphoric acid opangidwa ndi njira zonyowa, zodetsa zimakhudza kwambiri kukana. Mwa zina zonse za asidi, 904l Super Austenitic doakititic dolenition imakhala bwino kungokaniza zosapanga dzimbiri. Mu zotsatsa mwamphamvu nitric acid, 904l osapanga dzimbiri ali ndi chipongwe chochepetsera chipolopolo kuposa zitsulo zoyandikana kwambiri zomwe sizikhala ndi siliva. Mu hydrochloric acid, kugwiritsa ntchito904l dzimbiri zitsulondizochepa kutsika kwa 1-2%.
