SS904L AISI 904L Stainless Steel (UNS N08904)
Kenyelletso ea Sehlahisoa
AISI 904L stainless steel (UNS N08904) ke alloy high austenitic stainless steel. Ha ho bapisoa le 316L, SS904L e na le khabone e tlase (C), dikahare tse phahameng tsa chromium (Cr), mme e batla e lekana habeli ho feta ea nickel (Ni) le molybdenum (Mo) ea316L, e etsang hore e be le khanyetso e phahameng ea mocheso o phahameng oa oxidation, ho hanyetsa pitting, le ho hanyetsa ho fokotsa acid (mohlala, sulfuric acid). Naetrojene (N) e ka fokotsa sekhahla sa pula ea chromium carbide, ka hona ea fokotsa kutloelo-bohloko, hape ea ntlafatsa ho hanyetsa ho pitting le crevice corrosion e bakoang ke chloride. Haholo-holo tlatsetso ea eona ea koporo (Cu) e etsa hore e be molemo bakeng sa likarolo tsohle tsa sulfuric acid.
Alloy 904L e sebetsa hantle ho feta litšepe tse ling tsa austenitic stainless ka lebaka la motsoako o phahameng oa nickel le molybdenum. Mophato ha o na makenete maemong ohle mme o na le sebopeho se setle haholo le ho cheseha. Sebopeho sa austenitic se boetse se fana ka boemo bona bo thata ka ho fetisisa, esita le ho fihlela mocheso oa cryogenic Lintho tse phahameng tsa chromium li khothalletsa le ho boloka filimi e sa sebetseng e sireletsang thepa libakeng tse ngata tse senyang. Ha ho na kotsi ea ho senyeha ha intercrystalline ha ho pholile kapa ho cheselletsa ka lebaka la khabone e tlaase. Mocheso oa eona o phahameng ka ho fetisisa oa tšebeletso ke 450°C. Kereiti ena e bohlokoa haholo taolong le lits'ebetsong tsa li-tubing tsa lisebelisoa moo 316 le 317L li sa lokelang.
Alloy 904L qalong e ile ea ntlafatsoa ho mamella tikoloho e nang le dilute sulfuric acid. E boetse e fana ka khanyetso e ntle ho li-inorganic acid tse ling tse kang hot phosphoric acid hammoho le li-organic acid tse ngata.
Alloy 904L e chesetsoa habonolo le ho sebetsoa ka mekhoa e tloaelehileng ea ho etsa mabenkele.
904L tšepe e sa hloekang (SS904L) e sebelisoa ho petroleum, lik'hemik'hale, manyolo, litora tsa nts'etsopele ea maoatle, litanka, liphaephe le li-tubes le li-exchangers tsa mocheso. Rolex le baetsi ba lioache ba bang le bona ba e sebelisa ho etsa lioache
