SS904L AISI 904L Icyuma kitagira umwanda (UNS N08904)
Kumenyekanisha ibicuruzwa
AISI 904L ibyuma bitagira umwanda (UNS N08904) nicyuma kinini cya austenitike kitagira ibyuma. Ugereranije na 316L, SS904L ifite karubone yo hasi (C), chromium (Cr) yo hejuru, kandi hafi inshuro ebyiri nikel (Ni) na molybdenum (Mo) yibirimo316L, bigatuma igira ubushyuhe bwo hejuru bwa okiside yubushyuhe bwo hejuru, kurwanya pitingi, no kurwanya aside (urugero, aside sulfurike). Azote (N) irashobora kugabanya umuvuduko wimvura ya chromium karbide, bityo bikagabanya sensibilité de sensibilisation, binanoza imbaraga zo kurwanya imyanda no kwangirika kwatewe na chloride. Cyane cyane kongeramo umuringa (Cu) bituma igira akamaro kubintu byose bya acide sulfurike.
Alloy 904L ikora neza kurusha izindi ibyuma bya austenitis bitagira umuyonga kubera kuvanga cyane kwa nikel na molybdenum. Urwego ntabwo rufite magnetique mubihe byose kandi rufite uburyo bwiza bwo gusudira. Imiterere ya austenitis nayo itanga iki cyiciro gikomeye cyane, ndetse no munsi yubushyuhe bwa kirogenike Ibintu byinshi bya chromium biteza imbere kandi bigakomeza firime ya pasiporo irinda ibikoresho mubidukikije byinshi byangirika. Nta ngaruka zo kwangirika kwa intercrystalline ku gukonjesha cyangwa gusudira bitewe na karubone nkeya. Ubushyuhe bwa serivisi ntarengwa buri kuri 450 ° C. Uru rwego ni ingirakamaro cyane mugucunga no gukoresha ibikoresho byo kuvoma aho 316 na 317L bidakwiriye.
Alloy 904L yabanje gukorwa kugirango ihangane nibidukikije birimo acide sulfurike. Itanga kandi imbaraga nziza kurindi acide organique nka acide fosifori ishyushye kimwe na acide nyinshi.
Alloy 904L irasudwa byoroshye kandi igatunganywa nuburyo busanzwe bwo guhimba amaduka.
904L ibyuma bitagira umwanda (SS904L) bikoreshwa muri peteroli, imiti, ifumbire, iminara yiterambere ryinyanja, tank, imiyoboro hamwe nigituba hamwe noguhana ubushyuhe. Rolex nabandi bakora amasaha nabo barayakoresha mugukora amasaha
