904L ndi Super Austenstic Stainless Steel yokhala ndi mpweya wochepa.kalasi anafuna ntchito pansi kwambiri dzimbiri mikhalidwe.Yakhala ikugwiritsidwa ntchito kwa zaka zambiri ndipo idapangidwa kuti ipewe dzimbiri mu dilute sulfuric acid.Imakhazikika ndikuvomerezedwa kuti igwiritsidwe ntchito pazombo zokakamiza m'maiko angapo.Mwamakhalidwe, 904L ndi austenitic kwathunthu ndipo simakhudzidwa kwambiri ndi mvula ya ferrite ndi sigma magawo kuposa magiredi wamba austenitic okhala ndi molybdenum wambiri.Makhalidwe, chifukwa chophatikiza zinthu zambiri za chromium, faifi tambala, molybdenum ndi mkuwa 904L ali ndi kukana bwino kwa dzimbiri ambiri, makamaka sulfuric ndi phosphoric zinthu.

•Kukaniza bwino kutsekereza dzimbiri ndi dzimbiri paming'alu
•High kukana kupsinjika dzimbiri ang'onoang'ono, intergranular, machinability wabwino ndi weldability
•M'mitundu yonse yosiyanasiyana ya phosphates904L alloy corrosion resistance ndiyopambana kuposa chitsulo chosapanga dzimbiri wamba.
•Mu amphamvu oxidizing asidi nitric, poyerekeza ndi aloyi mkulu popanda molybdenum zitsulo kalasi, 904L amasonyeza kutsika dzimbiri kukana.
•Aloyi iyi imakhala ndi kukana kwa dzimbiri bwino kuposa chitsulo chosapanga dzimbiri wamba.
•Chepetsani kuchuluka kwa dzimbiri ku dzenje ndi mipata ya faifi tambala, ndipo khalani ndi mphamvu yokana kupsinjika kwa dzimbiri.kusweka, m'malo a chloride solution, ndende ya hydroxide solution ndi hydrogen sulphide wolemera.
•Petroleum ndi petrochemical zida, monga riyakitala wa zida petrochemical, etc.
