Khoom Description
E308L-17 Stainless Hlau Vuam Electrode
E308L-17 yog txiv qaub-titania coated stainless hlau electrode tsim los rau vuam AISI 304 thiab 304L austenitic stainless hlau. Nrog rau kev tswj hwm cov ntsiab lus qis (tsawg dua lossis sib npaug li 0.04%), E308L-17 electrode txo qhov kev pheej hmoo ntawm intergranular corrosion nyob rau hauv tshav kub- thaj tsam cuam tshuam - qhov tseem ceeb rau kev siv hauv kev ua tshuaj, khoom noj khoom haus qib, thiab cov hlab ntsha siab.
Cov yam ntxwv tseem ceeb ntawm E308L-17 Electrode
- Tsawg carbon deposit:Tsawg dua los yog sib npaug rau 0.04% C txo cov carbide nag lossis daus thiab intergranular corrosion susceptibility
- Smooth, ruaj khov arc:Txiv qaub-titania (-17) txheej muab ib qho chaw ntsiag to nrog me me spatter
- Pav ca-rau-me ntsis-convex hlaws profile:Ua kom huv, zoo nkauj pleasing welds nrog tsawg kawg nkaus ncej -weld sib tsoo
- Ib qho yooj yim slag tshem tawm:Tus kheej-lifting slag system accelerates ntxuav ntawm ntau- kis pob qij txha
- AC / DC tau tshaj:Ua haujlwm ntawm AC, DCEP, lossis DCEN, muab kev hloov pauv ntawm cov khoom siv hluav taws xob
- Tag nrho - txoj hauj lwm vuam:Rated rau tiaj tus, kab rov tav, ntsug-nce, thiab overhead txoj hauj lwm

FAQ
Q: Dab tsi yog cov ntawv thov tseem ceeb rau E308L-17 vuam electrodes?
A: E308L-17 yog siv rau vuam 304 thiab 304L austenitic stainless hlau. Nws yog tus qauv electrode rau zaub mov- cov khoom siv qib, tshuaj cog cov kav dej, cov hlab ntsha siab, thiab txhua daim ntawv thov yuav tsum muaj kev sib xyaw ua ke ntawm kev tiv thaiv corrosion thiab cov pa roj carbon tsawg.
Q: E308L-17 puas tuaj yeem siv los vuam 316 stainless hlau?
A: Tsis yog. Rau 316 thiab 316L stainless hlau, E316L-17 los yog E316L-16 electrodes yuav tsum tau siv los xyuas kom meej cov weld deposit muaj txaus molybdenum (Mo) cov ntsiab lus kom tau raws li qhov yuav tsum tau rau pitting corrosion kuj. Lub vuam tso nyiaj ntawm E308L electrodes tsis muaj molybdenum txaus thiab yog li tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev ua haujlwm cuam tshuam nrog 316 stainless hlau ib puag ncig.
Q: Puas yog E308L-17 haum rau siv nrog AC (Alternating Tam sim no) vuam?
A: Yog. E308L-17 electrodes feature ib "-17" (lime-titania) flux txheej txheej tsim tshwj xeeb tsim los muab kev ruaj ntseg zoo tshaj plaws nyob rau hauv AC lub zog, ua rau lawv xaiv zoo heev rau kev cob qhia siv cov tshuab vuam hom transformer.
Q: Puas yuav tsum tau preheating thaum vuam nrog E308L-17 electrodes?
A: Austenitic stainless hlau feem ntau tsis tas yuav preheating. Qhov tseeb, qhov kub ntawm qhov sib cuam tshuam thaum lub vuam yuav tsum tau tswj qis dua 350℃F (175 degree) kom ntseeg tau qhov kev tiv thaiv corrosion ntawm cov khoom siv vuam thiab txo qis vuam distortion.
Q: Puas yuav tsum tau shielding roj thaum vuam nrog E308L-17 electrodes?
A: Tsis yog. E308L-17 yog ib qho shielded hlau arc vuam (SMAW/Stick) electrode; nws cov txheej txheej flux generates nws tus kheej shielding roj thiab slag thaum lub sij hawm vuam txheej txheem, yog li muab qhov tsim nyog kev tiv thaiv. Yog tias koj xav tau TIG (Tungsten Inert Gas) lossis MIG (Hlau Inert Gas) vuam rau 304/304L stainless hlau, thov xa mus rau peb ER308L series ntawm vuam hlau.
Q: Puas tuaj yeem welds tsim siv E308L-17 electrodes hla radiographic (X-ray) tshuaj xyuas?
A: Muab cov txheej txheem vuam kom raug thiab cov kev ntsuas raug siv, cov hlau tso los ntawm E308L-17 electrodes muaj peev xwm ua tau raws li qhov kev lees paub rau kev kuaj hluav taws xob. Txawm li cas los xij, rau cov ntawv thov uas yuav tsum muaj kev tshuaj xyuas hluav taws xob nruj heev, E308L-16 electrodes feem ntau pom zoo; Qhov no yog vim lawv siv cov txheej txheem alkaline slag, uas txo cov ntsiab lus ntawm cov khoom tsis yog -hlau inclusions-xws li slag inclusions-hauv cov hlau weld.
