Machubu a Chitsulo Chosapanga Dzimbiri a 904L. UNS N08904, yomwe imadziwika kuti 904L, ndi chitsulo chosapanga dzimbiri cha austenitic chomwe chimagwiritsidwa ntchito kwambiri pamene mphamvu ya AISI 316L ndi AISI 317L ya dzimbiri siili yokwanira. Austenitic iyi ya alloy yapamwamba imalimbana kwambiri ndi sulfuric acid yochepetsedwa, phosphoric acid ndi acetic acid. Imalimbana ndi ming'alu m'njira za neutral chloride. Kukana kwake ku stress corruption cracking m'ma chloride ena otentha ndikwabwino kwambiri kuposa kwa nickel austenites otsika. Chitsulochi chili ndi mawonekedwe abwino komanso kusinthasintha. Zinthuzi zimapezeka mu miyezo yonse yofanana monga ASTM ndi EN, komabe pali kusiyana kwina. Kupsinjika kwa kapangidwe mpaka 370°C kumaphatikizidwa mu ASME II.
