Yog 7018 zoo rau stainless hlau?

7018 Vuam pas nrig yog ib qho staple hauv cov hlau me thiab qis {}} allo} ntxhov siab carbon steel qauv. Txawm li cas los xij, thaum nws los txog rau stainless hlau {{} nrog nws cov cim tsis kam thiab alloy {88 pas nrig yog lo lus nug. Thaum 7018 tuaj yeem ua tiav cov hlau sib xyaw ua ke, nws tsis ua tiav cov kev xav tau ntawm cov khoom lag luam stainless hlau, ua rau qhov kev xaiv tsis zoo rau txhua daim ntawv thov kev ua tau zoo lossis kev ua haujlwm ntev.
Thawj qhov tsis txaus ntseeg nyob rau hauv alloy tsis sib haum. Stainless hlau tso siab rau chromium (ntau dua los yog sib npaug rau ntawm 10.5%) thiab feem ntau npib los tsim cov xeb uas tiv thaiv uas tiv taus xeb thiab xeb. Piv txwv li, 304 stainless hlau muaj 18-20% chromium thiab 8-10.5% npib me me, tab sis tsawg dua 0.5% chromium thiab tsis muaj npib tsib lossis molybdenum. Thaum siv rau weld stainless hlau, 708 pas dej puas cov chromium thiab npib tsib lub siab xav tau los ua ib txheej oxide tiv thaiv. Qhov tshwm sim yog ib txoj kev weld uas ua raws li kev ua xeb "Link" tsis muaj zog "- Txawm hais tias ib puag ncig qhuav ntau dua li cov hlau nyob ib puag ncig. Hauv noo, ntug dej hiav txwv, lossis tshuaj lom neeg-}}}} acceler acceler acceler accelerມ, ua rau thaum ntxov ua tsis tiav ntawm kev sib koom tes.
Cov neeg kho tshuab tsis sib haum yog lwm qhov teeb meem tseem ceeb. Stainless hlau, tshwj xeeb tshaj yog cov qib qis dua li 304, muaj kev sib tw ua kom muaj zog, lossis kev cuam tshuam ntawm kev sib tw yog qhov tsis muaj kev sib tw Qhov no tsim kom muaj kev phom sij weld uas tsis tuaj yeem hloov pauv nrog lub stainless hlau luj hlau, ua yeeb yam raws li kev ntxhov siab conversrator. Nyob rau hauv cyclic loads- Xws li cov kev co ntawm stainless hlau tshuab lossis lub thermal caij tsheb kauj vab {}} Weld yog nquag mus rau brittle beel deeciture. Rau thauj khoom - Cov kabmob sib tw cov qauv sib tw zoo li nkhaus lossis txhawb nqa, qhov no muaj kev phom sij txaus ntshai.
7018's vuam cov yam ntxwv kuj tseem mob -} haum rau cov hlau stainless. Nws qhov qis - hydrogen txheej yuav tsum tau ua kom zoo nkauj (tab sis txawm tias thaum cua sov ua kom zoo rau cov hlau hlau, tsis yog stainless. Lub 7018 tus pas nrig ua rau lub ntsej muag nqaim, tsom rau cov hlwv uas tsis muaj zog ntawm cov cua sov- bein cuam tshuam cheeb tsam (haz) thiab txo nruj. Tsis tas li ntawd, nws lub slag system yog tsim los tiv thaiv cov hlau hlau vas, tsis muaj lub pas dej ua ke, ua kom cov pa hluav taws xob tsis muaj zog thiab
Txawm nyob hauv ib ntus lossis tsis - qhov tseem ceeb kho, 7018 pas nrig muaj kev pheej hmoo. Thaum lawv tuaj yeem tsim ib qho luv luv- Lub Term Neeg Kho Siab Kev Sib Thiaj, Weld qhov tsis zoo corrosion tsis ntseeg nws yuav ua rau nws yuav ua rau nws tsis kam. Xeb los ntawm 7018 weld muaj peev xwm stain uas nyob ib sab ntawm cov hlau stainless, uas yuav tsum tau siv kim lossis hloov. Piv txwv li, siv 7018 los ua li cas ntawm lub qhov muag ua ntej ntawm Weld yuav rhuav tshem lub BOD lub ntsej muag thiab cov qauv kev ntseeg nyob rau lub hlis.
Stainless tus hlau yuav tsum muaj cov pas nrig tshwj xeeb tsim kom phim nws li alloy muaj pes tsawg leeg. Rau cov qib Austenic zoo li 304, e308l {{13 pas dej muab 18-21% npib thiab 8-11% npib tsis kam, thaum lawv cov pa roj carbon qis tiv thaiv cov ntsiab lus. Rau 316 stainless hlau, E316L-16 ntxiv Molybdenum kom tiv thaiv pitting. Cov pas nrig no ua kom peb Weld khaws cov khoom tiv thaiv oxide tib yam thiab cov kws kho tshuab raws li cov hlau-ib yam 7018 tsis tuaj yeem ua tiav.
Hauv cov ntsiab lus, 7018 tsis zoo rau cov hlau tsis muaj hlau. Nws li alloy muaj composition tsis replicate stainless hlau txoj kev lag luam tiv thaiv, thiab nws cov cwj pwm vuam sib dhos sib dhos. Thaum 7018 excels nrog carbon hlau, stainless hlau xav tau cov pas nrig tsim tshwj xeeb rau nws cov kev xav tau tshwj xeeb. Rau kev ntseeg siab, ruaj stainless hlau welds, stainless hlau - Cov ntawv sau tshwj xeeb yog qhov tsuas yog xaiv tau.
