904L ibyuma bitagira ibyuma bya austenitike ni ibya karubone nkeya, nikel ndende, molybdenum austenitis ibyuma bitagira umwanda hamwe na aside irwanya aside.904L austenitis ibyuma bidafite ibyuma bifite ubushobozi bwo guhindura passivation nziza cyane, kurwanya ruswa nziza, kurwanya ruswa neza muri acide idafite okiside nka acide sulfurike, acide acike, aside aside, na aside fosifori, kurwanya neza kwangirika mubitangazamakuru bya chloride bitagira aho bibogamiye, kandi byiza Kurwanya ruswa no kwangirika.Bikwiranye nubushakashatsi butandukanye bwa acide sulfurike iri munsi ya 70 ℃, ifite imbaraga zo kurwanya ruswa zose hamwe nubushyuhe bwa acide acike hamwe nuruvange rwa acide formique na acide acike munsi yumuvuduko usanzwe.

Icyuma cya Austenitike kitagira ibyuma 904L nicyuma kinini cya austenitis cyuma kitarimo ibyuma bike.Ifite ruswa irwanya ruswa ya acide sulfurike kandi yagenewe ibidukikije bifite ibihe bibi.Ifite chromium nyinshi kandi irimo nikel ihagije.Kwiyongera k'umuringa biha imbaraga zo kurwanya aside, cyane cyane irwanya cyane chloride interstitial corrosion hamwe no gucika intege.Ntibikunze kugaragara ahantu hashobora kwangirika no gucika, kandi kurwanya kwangirika kwangirika ni byiza cyane ugereranije nibindi byuma.Ifite imashini nziza no gusudira kandi irashobora gukoreshwa mumitsi.

Kurwanya ruswa

904L ni karuboni nkeya, ikomatanya cyane austenitike idafite ibyuma yagenewe ibidukikije byangirika.Ifite ruswa irwanya ruswa kurusha 316L na 317L, mugihe iringaniza igiciro nibikorwa, kandi ifite igiciro-cyiza cyane.Bitewe no kongeramo umuringa 1.5%, ifite imbaraga zo kurwanya ruswa kugirango igabanye aside nka acide sulfurike na aside fosifori.Ifite kandi uburyo bwiza bwo kurwanya ruswa ishobora kwangirika, kwangirika kwangirika, no kwangirika kwatewe na ion ya chloride, kandi ifite imbaraga zo kurwanya ruswa.Muri acide sulfurike isukuye hamwe na 0-98%, ubushyuhe bwo gukoresha bwa 904L burashobora kugera kuri dogere selisiyusi 40.Muri acide ya fosifori yuzuye ifite ubunini bwa 0-85%, irwanya ruswa ni nziza cyane.Umwanda ugira ingaruka zikomeye ku kurwanya ruswa ya fosifori yo mu nganda ikorwa n’ikoranabuhanga ritose.Mu bwoko bwose bwa acide fosifori, 904L ifite imbaraga zo kurwanya ruswa kurusha ibyuma bisanzwe bidafite ingese.Muri okiside ya acide ya nitricike, 904L ifite imbaraga zo kurwanya ruswa ugereranije n’icyuma kinini kivanze nta molybdenum.Muri aside hydrochloric, ikoreshwa rya 904L rigarukira gusa kuri 1-2%.Muri uru rwego.Kurwanya ruswa ya 904L nibyiza kuruta ibyuma bisanzwe bidafite ingese.904L ibyuma bifite imbaraga nyinshi zo kurwanya ruswa.Kurwanya kwangirika kwangirika mumuti wa chloride.Imbaraga nazo ni nziza cyane.Nikel nyinshi iri muri 904L igabanya igipimo cya ruswa mu myobo no mu myobo.Ibyuma bisanzwe bya austenitike bidafite ingese birashobora kuba byoroshye kwangirika kwangiza ibidukikije bikungahaye kuri chloride mubushyuhe buri hejuru ya dogere selisiyusi 60.Mugukomeza nikel yibigize ibyuma, iyi sensibilisation irashobora kugabanuka.Bitewe na nikel nyinshi, 904L yerekana imbaraga nyinshi zo kurwanya ihungabana ryangirika rya chloride, ibisubizo bya hydroxide yibanze, hamwe nibidukikije bikungahaye kuri hydrogen sulfide.
