Kev vuam hlau tsis xebyog ib qho txheej txheem tseem ceeb hauv kev tsim khoom niaj hnub no, xav tau cov khoom siv uas ua kom muaj kev tiv thaiv corrosion thiab kev ua haujlwm zoo. Lub E308-16 electrode yog ib qho cuab yeej tseem ceeb uas tsim tshwj xeeb rau lub hom phiaj no. Raws li lub electrode coated titanium, nws yog tsim los siv nrog cov hlau tsis muaj carbon ultra-low, tsim ib feem tseem ceeb ntawm ntau yam kev txij nkawm thiab kev tsim khoom lag luam. Kev ntseeg tau ntawm tag nrho cov qauv welded feem ntau nyob ntawm kev xaiv cov electrodes tshwj xeeb, ua rau kev nkag siab txog lawv cov khoom tseem ceeb rau cov neeg vuam thiab cov engineers.
Lub electrode E308-16 yog tsim los ntawm tshuaj lom neeg rau kev siv thawj zaug hauv kev vuam hlau tsis xeb: koom nrog 18% chromium thiab 8% nickel hlau. Cov khoom sib xyaw no yog ib qho ntawm cov qib austenitic feem ntau, thiab cov tshuaj lom neeg tso nyiaj ntawm lub electrode tau sib npaug zoo kom phim nws qhov kev tiv thaiv corrosion thiab cov khoom siv kho tshuab. Lub npe "L" hauv nws cov hlau sib phim qhia txog cov ntsiab lus carbon tsawg, uas yog qhov tseem ceeb rau kev tiv thaiv carbide precipitation thaum lub sijhawm vuam. Qhov no ua kom ntseeg tau tias qhov sib koom ua ke welded khaws nws qhov kev tiv thaiv rau intergranular corrosion, qhov chaw ua tsis tiav hauv cov hlau tsis xeb tsis raug.
Scope ntawm daim ntawv thov rau lub electrode no hauvvuam hlau tsis xebyog dav, tshwj xeeb tshaj yog nyob rau hauv kev lag luam. Nws yog qhov tsim nyog heev rau kev tsim cov qauv ua los ntawm 022Cr19Ni10 (tus qauv Suav qib sib npaug rau 304L) stainless hlau. Nws yog dav siv hauv kev tsim cov khoom siv rau qhov chaw nyuaj, cov nroj tsuag fiber ntau, cov chaw tsim tshuaj chiv thiab ntau yam khoom siv petrochemical. Hauv cov ntawv thov no, qhov kev sib txuas ua ke los ntawm E308-16 yog qhov tseem ceeb rau kev muaj cov xov xwm corrosive thiab tswj kev nyab xeeb ua haujlwm.
Cov yam ntxwv ua haujlwm ntawm E308-16 ua rau nws yog qhov kev xaiv ntau yam rau ntau qhov chaw vuam. Lub "-16" tom qab hauv nws qhov kev faib tawm qhia tias nws muaj cov txheej txheem lime-titania, uas txhawb nqa kev vuam hauv txhua qhov chaw.—tiaj tus, kab rov tav, ntsug, thiab saum taub hau. Qhov no yog qhov zoo tseem ceeb hauv kev tsim khoom thiab kho cov haujlwm uas qhov chaw hloov kho tsis yooj yim. Lub arc ruaj khov, cov slag yooj yim tshem tawm, thiab qhov zoo li lub hlaws dai yog du, uas ua ke pab txhawb rau kev ua haujlwm vuam hlau stainless zoo, ua haujlwm tau zoo nrog kev ntxuav tom qab vuam tsawg kawg nkaus.
Lub E308-16 electrode yog ib qho khoom siv tau zoo uas daws tau cov teeb meem tshwj xeeb ntawmvuam hlau tsis xebrau cov qib carbon tsawg heev. Nws cov tshuaj siv rau 18-8 hlau thiab nws qhov haum rau cov lag luam tseem ceeb xws li petrochemicals thiab chiv qhia txog nws qhov tseem ceeb. Rau cov kws tshaj lij koom nrog kev vuam hlau tsis xeb, xaiv E308-16 electrode rau cov haujlwm cuam tshuam muab txoj hauv kev txhim khu kev qha ntawm kev ua tiav cov vuam ruaj khov, tiv taus corrosion uas ua tau raws li qhov xav tau ntawm kev ua tau zoo thiab kev nyab xeeb hauv kev siv hauv kev lag luam.
