Lub hauv paus rau phau ntawv
Raws li cov ntaub pua chaw vuam tshwj xeeb rau cov khoom siv hluav taws xob tshwj xeeb rau cov roj me me, 308-16}} vuam qws ua lub luag haujlwm tseem ceeb hauv kev lag luam vuam. Nws zoo heev corrosion tsis kam thiab vuam ua kom nws dav siv hauv cov khoom tseem ceeb xws li kev lag luam tshuaj lom neeg, khoom noj nuclear. Kab lus no muab cov kev tshawb fawb tshiab tshaj plaws thiab kev nce qib thev naus laus zis los tshawb xyuas cov ntsiab lus tseem ceeb ntawm 308-16} vuam pas nrig.
Cov kev siv tub ntxhais thiab cov yam ntxwv sib xyaw
{{{{{{0}} chromium tus qauv (CR) thiab 9% Nickel (MN) thiab silicon (si). Cov qauv tsim muaj roj carbon (cov pa roj carbon tsawg dua lossis sib npaug ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm kev sib cav sib ceg thiab ua kom muaj kev ruaj ntseg ntev ntawm Weld.
Daim ntawv thov tseem ceeb
- Cov Khoom Siv Tshuaj thiab Petrochemical
308-16} vuam rods tau siv dav rau cov hlau tshuab AISI 304 thiab yog haum rau kev tsim cov tshuaj reactors, cov raj xa dej thiab tso tsheb hlau luam thiab chaw cia khoom thiab tso tsheb hlau luam. Cov kev tshawb fawb tau pom tias nws cov Welds pom zoo lub zog thiab corrosion tsis zoo nyob rau hauv ob lub xeev welded thiab kub tau tsim rau cov acidic los yog high-kub tshaj tawm.
- Cov Khoom Siv Ua Khoom Noj
Vim nws cov khoom noj zoo tshaj plaws rau cov khoom noj kom zoo (xws li kua mis thiab kua qaub ua ke),}}}}} pa rods ntawm cov khoom noj ua tshuab, xws li xa cov raj xa khoom ua ke, xws li kev xa khoom siv hluav taws xob thiab nplawm.
- Nuclear Fais Fab Cov Chaw
Nyob rau hauv lub zog hluav taws xob ntoo, 308l {1} l welded sib koom ua ke yog siv los txuas reactor siab cov hlab ntsha mus rau corelines corelines loj. Txawm hais tias cov pob qij txha li no muaj kev pheej hmoo ntawm pitting thiab kev nyuaj siab ib puag ncig dej thiab cov txheej txheem dej muaj peev xwm tseem tuaj yeem lav los ntawm cov txheej txheem ntau txheej txheem arc vuam (smaw) txheej txheem.
- Dissimilar hlau vuam
Cov kev sim tau qhia tau tias {308-16} Cov khoom siv vuam sib txuas ntawm cov khoom sib txuas ntawm cov hlau grey, xws li kev kho twj tso kua mis lub cev lossis li qub. Txawm li cas los xij, nws yuav tsum raug sau tseg tias yog tias yog tias tsim kho cua sov tsis tau ua tom qab vuam, ledeburite qauv yuav tsim nyob rau ntawm lub interface, uas ua rau muaj kev txo qis hauv lub zog.
Cov txheej txheem ua kom zoo thiab tshawb fawb
- Kev tiv thaiv nkev tiv thaiv: Nyob rau hauv tig vuam, kev siv ntawm Argon kev tiv thaiv tuaj yeem txhim kho Weld kev sib xws thiab txo cov mob wulld sib txawv (xws li pores thiab nrib pleb).
- Txhim kho corrosion: los ntawm Weld Anneiting kev kho, cov dej nag hauv zos tuaj yeem txo, thiab cov dej nag hauv cov weld hauv 3.5% NacL daws tuaj yeem txo los ntawm 30%.
- Cov kev siv cov kav hlau tshiab: rau tag nrho cov chaw siv hluav taws xob siv hluav taws xob los daws cov teeb meem argon-free
Sau ntawv thiab txwv
Txawm hais tias {308-16 electrode muaj kev ua tau zoo heev, nws yuav tsum tau sib phim cov ntaub ntawv vuam kom phim cov hlau corrosion (xws li 316L muaj 2% molybdenum). Ib qho ntxiv, hauv cov teeb hluav taws xob zoo xws li cov khoom siv hluav taws xob nuclear, xws li kev txheeb xyuas cov txiaj ntsig polariatiodynamic polarization) yuav tsum ntsuas qhov pitting ntawm weld.
Tag
308-16} vuam pas tau ua ib qho "nkaus ntawm txhua qhov kev lag luam ntawm stainless hlau vuam vim nws cov qauv tsim qauv thiab cov txheej txheem tsim qauv. Nrog rau kev txhim kho lub zog nuclear thiab cov cuab yeej tsim kev lag luam siab yuav txuas ntxiv, thiab kev kho kom sov yuav txuas ntxiv mus txhawb kev ua kom paub tseeb.
