Ipuleti lensimbi engagqwali elingu-904Luhlobo lwensimbi engagqwali e-austenitic enokuqukethwe okuphansi kakhulu kwekhabhoni kanye nokuhlanganiswa okuphezulu okwenzelwe izindawo ezinezimo ezinzima zokugqwala. Inokumelana nokugqwala okungcono kune316Lfuthi317L, ngenkathi kucatshangelwa intengo, ukusebenza kahle, kanye nokusebenza kahle kwezindleko. iphakeme. Ngenxa yokwengezwa kwethusi elingu-1.5%, inokumelana okuhle kakhulu kokugqwala ngokumelene nama-asidi ancishisiwe njenge-sulfuric acid kanye ne-phosphoric acid. Iphinde ibe nokumelana okuhle kakhulu kokugqwala ngokumelene nokucindezeleka kokugqwala kanye nokugqwala okubangelwa ama-ion e-chloride, futhi inokumelana okuhle nokugqwala kwe-intergranular. Ku-asidi e-sulfuric emsulwa ebangeni lokuhlushwa elingu-0-98%, izinga lokushisa lesevisi lepuleti lensimbi elingu-904L lingaba phezulu kuze kufike kuma-degree Celsius angu-40. Ku-asidi e-phosphoric emsulwa ebangeni lokuhlushwa elingu-0-85%, ukumelana kwayo nokugqwala kuhle kakhulu. Ku-asidi ye-phosphoric yezimboni ekhiqizwa yizinqubo ezimanzi, ukungcola kunomthelela omkhulu ekumelaneni nokugqwala. Phakathi kwazo zonke izinhlobo ze-asidi ye-phosphoric, insimbi engagqwali engu-904L super austenitic inokumelana okungcono kokugqwala kunensimbi engagqwali evamile. Kuma-asidi aqinile oxidizing, insimbi engagqwali engu-904L inokumelana okuphansi kokugqwala kunezinhlobo ezahlukene zensimbi ezixutshwe kakhulu. ngaphakathi kwalolu hlu lokuhlushwa. Ukumelana nokugqwala kwensimbi engu-904L kungcono kunokwensimbi engagqwali evamile. Insimbi engagqwali engu-904L inokumelana okuphezulu nokugqwala kwemigodi. Imelana nokugqwala kwemisele ezixazululweni ze-chloride. Amandla ayo nawo mahle kakhulu. Okuqukethwe okuphezulu kwe-nickelIpuleti lensimbi elingu-904Lkunciphisa izinga lokugqwala emigodini nasemathungeni. Ngenxa yokuqukethwe kwayo okuphezulu kwe-nickel, i-904L inokumelana okuphezulu nokuqhekeka kokugqwala okucindezelekile ezixazululweni ze-nitride, izixazululo ze-hydroxide ezigxilile kanye nezindawo ezicebile nge-hydrogen sulfide.
