AL-6XN (N08367|25-6HN) super austenitic stainless hlau
AL-6XN (UNSN08367) yog super austenitic stainless hlau nrog zoo heev tiv taus chloride ion pitting thiab crevice corrosion. Raws li corrosion-resistant alloy nrog zoo nqi kev ua tau zoo, nws cov kev tiv thaiv corrosion tau zoo heev piv rau 316L. Nyob rau tib lub sijhawm, nws qhov kev tiv thaiv corrosion nyob ze rau lwm yam corrosion-resistant nickel-raws li alloys xws li C-276, thiab nws cov nqi kom zoo dua yog pom tseeb. Vim tias muaj cov ntsiab lus nitrogen tseem ceeb ntxiv rau cov hlau, AL-6 cov khoom siv XN muaj zog tensile ntau dua li cov pa austenitic stainless hlau (xws li 304, 316, 317, thiab lwm yam), thaum tuav cov khoom zoo heev toughness thiab cuam tshuam lub zog. . Tus nqi kev ntxhov siab uas tau teev tseg hauv ASME tus qauv yog 40% siab dua li ntawm AL-6XN 316L thiab ze li ob npaug ntawm tooj liab-nickel alloy. Cov xwm txheej ua haujlwm: 60% sulfuric acid, qis dua 80 degree, txhua xyoo corrosion tus nqi<0.1mm.
Nta:
AL-6XN (UNS N08367) yog cov hlau tsis muaj corrosion-resistant uas muaj cov chromium siab thiab molybdenum siab. Nws tuav zoo corrosion kuj txawm nyob rau hauv hnyav ib puag ncig xws li kub, dej hiav txwv los yog flue gas desulfurization. Nws yog ib qho kev lag luam zoo stainless hlau nrog kev ua haujlwm siab corrosion uas yog piv rau Hastelloy thiab titanium daim hlau hauv qee qhov chaw.
Vim tias AL-6XN muaj cov ntsiab lus siab ntawm chromium, molybdenum thiab nitrogen, nws tuaj yeem pom qhov zoo heev pitting corrosion kuj thiab crevice corrosion kuj txawm nyob rau hauv ib puag ncig chloride. Nyob rau hauv ib puag ncig corrosive uas nws nyuaj rau duplex stainless hlau kom muaj corrosion kuj, AL-6XN tuaj yeem muab kev ua si tag nrho rau nws qhov zoo heev corrosion kuj.
Khoom siv:
Cov ntim tshuaj lom neeg thiab cov kav dej, cov cuab yeej siv ntawm cov roj av thiab cov pa roj, cov condensers, cov khoom siv hluav taws xob sib txuas thiab cov kav dej hauv kev sib cuag nrog cov dej hiav txwv lossis cov roj av, lim presses, cia tank thiab siab rollers hauv cov txheej txheem bleaching, thermal fais fab nroj tsuag, steel nroj tsuag, Cov khoom siv hluav taws xob desulfurization (FGD) ntawm cov tuam txhab petrochemical, cov roj crude distillation yees thiab ntim khoom, cov khoom siv desalination thiab cov twj tso kua mis, nuclear fais fab nroj tsuag servo dej pipeline systems, transformer case raug rau marine ib puag ncig, cov khoom siv tshuaj (rau purity ntawm cov tshuaj), zaub mov cov khoom siv ntau lawm.
Txhawb cov khoom siv vuam:
Nws raug nquahu kom siv AWS A5.14 vuam hlau ERNiCrMo-3 lossis AWS A5.11 vuam qws ENiCrMo-3 rau vuam Al-6XN stainless hlau.
