Cov qhab nia ntawm Super Duplex Stainless hlau fasteners yog siv thaum cov ntawv thov xav tau kev xav tau zoo tshaj plaws thiab lub zog. Muaj cov nitrogen, molybdenum thiab chromium, lawv tau ua kom zoo tshaj plaws rau cov creevice corrosion thiab chloride pitting.
Kuj tseem hu ua qauv duplex stainless hlau, cov 2205 duplex bolts yog ib qho ntawm feem ntau dav siv stainless hlau qib.
Lub zog nkees ntawm s31803 txiv ntoo kuj tseem zoo nyob hauv txhua qhov kev mob siab. Ob lub txiv ntseej tsis muaj zog s31803 kuj muaj lub zog nkees thiab kev tsis txaus siab rau kev ntxhov siab corrosion, tawg, yaig, tab sis lwm yam.
Duplex 2205 yog (ob-theem) Ferritic-Austenitic-Austenitic-Ausenut Corrosion nrog lub zog loj tshaj plaws ntawm 290 (RC31) hauv anealed mob.
Duplex 2205 txiv ntoo thiab txiv ntoo yog dav siv nyob rau hauv cov ntawv thov uas yuav tsum tau corrosion tsis kam thiab lub zog hauv cov tub rog thiab muaj zog.
Cov kav hlau dulex uns s31803 Hex txiv ntoo yog qhov cuam tshuam dav rau cov teebmeem ntawm cov pa roj sulphurous, tshwj xeeb tshaj yog tshaj li 900 degrees Celsius, tsawg heev.
Lub txiv ntseej yas tsis muaj nyob rau hauv ob theem, 5% rau 6% Nickel Alloy Steel, 3% Molybdenum, Austenitic 22% chromium.
Preheating ntawm uns s32750 super duplex fasteners tsis tsim nyog tsuas yog kom tiv thaiv hws ntawm hlau txias.
Theem Stainless Hlau Unfension S31803 nthuav tawm cov khoom ntawm Austenitic thiab Ferritic Stainless hlau. Unr unical steel fasteners muaj lub zog siab, zoo tsis kam mus rau sulfide kev nyuaj siab corrosion thiab kev cuam tshuam zoo heev.
Lwm qhov laj thawj rau cov khoom siv zoo ntawm ob lub pob tsuas muaj peev xwm sib xyaw tab sis ferritic microstriticure tam sim no hauv cov alloy.
Qee qhov zoo ntawm kev siv Super Duplex fasteners suav nrog lub zog ntawm lub zog, muaj zog heev zog thiab zoo heev corrosion tsis kam.
Duplex 2205 Fasteners yog tsim los ntawm cov qauv ob lub ntsej muag. Cov khoom muaj carbon, manganese, sidoob, phosphorus, 21% chromium, 2.5% molybdenum, 4.5% npib tsib xee thiab nitrogen.
Peb muab cov kev ua tiav ntawm 2205 duplex steel footeners xws li bolts, neeg rau, ntxuav, txuas cov pas nrig thiab ob leeg steel screws. Peb kuj muaj super duplex fasteners nyob rau ntau thiab tsawg, cov duab, nta thiab tuab raws li cov neeg siv khoom.
Rau duplex s31803 txiv ntoo, 2 feeb rau 3 feeb rau ntawm phab ntsa tuab ntawm 1080 degrees Celsius yog txaus kom ua tiav lub Austus \ / ferrite piv. Tom qab annealing, nws raug nquahu kom txias cov duplex suplex s32205 sai li sai tau.
Vim yog lub alloy's high tshuab zog heev, dual-theem cov khoom lag luam ceev ntawm lawv cov qauv ntawm cov khoom lag luam uas zaum kawg, ua pov thawj tus nqi txuag rau lwm cov hlau stainless.
Peb cov kav hlau duplex tsis muaj nyob rau hauv cov qib sib txawv xws li cov tshuab ntxhua khaub ncaws, kev lag luam screess, stainless hlau wasters, stainless hlau screws thiab ntau dua.
Rhuab los ntawm 1050¡Ãc txog 1150¡Ãc thiab dej quenched, qhov kev kho mob ntawm ob tus txiv neej stuplex unsures uas txhua tus carbided.
UNTED S2750 SUPER DUPLEX Fasteners muaj qhov zoo weldability thiab tuaj yeem koom nrog nws tus kheej lossis cov roj hlau arc vuam, flux cored hlau lossis subsbreaked arc vuam.
Xov kev sib txhuam ntawm cov txiv ntoo thiab bolt tsim lub zog, khov kho thiab txawm yuam kev tuav cov khoom sib xyaw ua ke. Feem ntau siv ASTM A182 unhicial s32205 khawm ceev ceev yog ib txwm hex txiv ntoo. Nyob rau tib lub sijhawm, Ob lub stuplex stainless hlau footeners muaj zog thiab corrosion deferanut, sib txuas ntawm cov muaj kev noj qab haus huv ntawm ferrite thiab austenite. Cov khoom siv tseem muaj 90 yam kawg liti yam tsawg kawg tensile lub zog thiab ib 65ksi yam tsawg kawg zog zog. 2205 Duplex stainless hlau bolts muaj elongation ntawm 25% thiab kev nyuaj ntawm 217HBW.
Sib xyaw ustenitic ferritic microstructure ¨c Cov steel tau txais nws lub npe vim tias micrlex stainless hlau ceev dua alloy yog lub duplex lossis duplex lossis Duplex lossis Duplex lossis Duplex lossis Duplex lossis Duplex lossis Duplex lossis Duplex lossis Duplex lossis Duplex lossis Duplex lossis Duplex lossis Duplex. Qhov no tshaj plaws no ntawm ustenitic ferrite ua rau hloov pauv hauv alloy.
Vim yog lub zog tiv thaiv kev siv tshuaj lom neeg suav nrog cov kua qaub, hauv paus doss thiab neutx tsis yog qhov zoo tshaj plaws ntxiv rau cov kev lag luam no.
Duplex cov hlau muaj ntau dua kev nruj thiab zoo dua weldability. Qhov no yog li cas alloy siv phaj yog siv rau kev lag luam kev lag luam muaj siab.
2205 Duplex neeg rau yog cov neeg siv hluav taws xob ntau tshaj 2205 fasteners thiab featre cov txiaj ntsig lub zog uas yog ob zaug ntawm cov qauv kev ua kom muaj kev sib tw.
Lawv kuj muaj kev tiv thaiv zoo heev rau corrosion cracking thiab cov corrosion hauv zos xws li pitting, intergranular thiab crevice. Tsis zoo li lwm cov qauv Austenitic cov hlau, uns unicial uncials, steel muaj cov khoom sib nqus zoo heev.
Hauv S31803, kwv yees li ib nrab ntawm cov ferrite nplej hloov mus rau hauv Austenite nplej ("Islands tuaj") raws li cov khoom txias mus rau chav sov. Qhov tshwm sim yog microstructure ntawm kwv yees li 50% austenite thiab 50% ferrite.
Vim yog cov khoom siv tshuab hluav taws xob zoo thiab cov kws kho tshuab ntawm super duplex, qhov zoo tshaj ntawm super duplex lub zog tuaj yeem ntsib cov roj ntau ntawm cov roj, roj thiab marine kev lag luam.
ASME SA 479 UNRONT S32205 FORTEEN yog kev tiv thaiv corrosion thiab siab zog dag zog rau hauv nruab nrab ntawm 1300 degrees Fahrenheit.
