Hla lub siab-cov khw muag khoom, khoom noj- ua OEMs thiab cov neeg ua haujlwm petrochemical piping, ib lo lus nug tseem rov qab mus rau hauv pem teb rhiav: koj puas tuaj yeem txuas 304 stainless hlau rau cov hlau me me nrog ib tus pas electrode, thiab cov electrode puas tseem xav tau AWS E309L-16 hauv 2026? Plaub xyoo tom qab E309 / E309L-16 yog tus qauv, cov lus teb los ntawm cov khoom siv hluav taws xob loj tsis tau hloov pauv.
Vim li cas vuam stainless rau carbon hlau tseem cia siab rau E309L-16?
Cov ntsiab lus chromium los yog npib tsib xee hauv tus qauv 308 series vuam cov ntaub ntawv tsis txaus los tiv thaiv cov nyhuv dilution los ntawm carbon steel sab hauv cov hlau sib txawv. E309L-16 electrodes tshwj xeeb yog tsim los rau cov kev ua kom zoo li no, tsim cov hlau txuas nrog cov khoom siv austenitic tag nrho (muaj 23% chromium thiab 13% npib tsib xee, nrog rau cov ntsiab lus siab tshaj plaws ntawm 0.04%); cov weld khaws cov qauv austenitic no txawm tias muaj txog li 30% ntawm cov pas dej da dej uas muaj feem cuam tshuam los ntawm qhov qis -carbon steel.[1] Grainger faib Lincoln Electric's 309/309L-16 raws li qhov dav dav-lub hom phiaj stainless hlau electrode; Nws yog sib xws nrog ob qho tib si AC thiab DCEP cov khoom siv hluav taws xob thiab txhawb nqa txhua txoj haujlwm vuam-ib qho tsis tshua muaj kev sib xyaw ua ke ntawm cov yam ntxwv hauv kev sib txawv ntawm cov hlau vuam.
Hnub twg yog hnub-rau-hnub tsis sib xws-welding scenarios?
| Ntu | Hom kev sib koom ua ke | Vim li cas E309L-16 |
|---|---|---|
| Petrochemical piping | 304L rau A106 carbon steel | Dilution-tolerant austenitic weld |
| Cov hlab ntsha siab | Stainless clad rau carbon- steel plhaub | Buttering txheej ua ntej 308L overlay |
| Khoom noj khoom haus & khoom siv mis nyuj | 316 haum rau me me- steel ncej | Tag nrho austenitic, tsis muaj ferrite migration |
| Shipyard haum- tawm | 304 tes rau carbon- steel lawj | Khiav ntawm shipboard AC generators |
Puas yog qhov qis - carbon variant tiag tiag?
Rau cov ntawv thov uas suav nrog chav- qhov kev pabcuam kub tom qab vuam, tus qauv E309-16 (C Tsawg dua lossis sib npaug rau 0.15) muaj cov khoom siv hlau txaus. Txawm li cas los xij, yog tias qhov sib koom ua ke yuav tsum tau ua tom qab-weld kev kho cua sov siab tshaj li ntawm 370℃lossis raug rau cov xov xwm ntub dej, cov pa roj carbon tsawg E309L-16 (C Tsawg dua lossis sib npaug rau 0.04) yuav tsum raug xaiv kom tsis txhob muaj kev pheej hmoo ntawm kev nkag siab thiab sigma (σ) theem tsim.
FAQ
Q: E309L-16 puas tuaj yeem siv rau vuam stainless rau me me hlau?
A: Yog .Nws yog AWS-pom zoo rau kev koom nrog 304 / 304L / 316 stainless kom me me lossis qis- alloy carbon hlau.
Q: Dab tsi yog qhov txawv ntawm E309-16 thiab E309L-16 rau qhov sib txawv ntawm vuam?
A: Ob leeg ua haujlwm; E309L-16 muaj cov pa roj carbon tsawg (tsawg dua lossis sib npaug li 0.04%) thiab nyiam rau PWHT lossis kev pabcuam corrosive.
Q: Koj puas yuav tsum siv E308-16 rau 304-to-carbon-steel pob qij txha?
A: Tsis yog. E308-16 (19Cr-9Ni) tsis muaj cov ntsiab lus hlau txaus kom nqus tau cov pa roj carbon dilution thiab yuav kub-dhuav ntawm txoj kab fusion.
Q: Dab tsi amperage koj yuav tsum siv ntawm 3.2 hli E309L-16?
A: Feem ntau 80 - 120 A ntawm DCEP hauv qhov chaw tiaj tus; 70 - 110 A ntsug / nyiaj siv ua haujlwm.
Q: Puas yog qhov sib koom ua ke xav tau preheat?
A: Tsis yog rau seem thicknesses hauv qab no ~ 25 hli; Cov pa roj carbon hnyav dua- cov seem hlau tau txais txiaj ntsig los ntawm 100 - 150℃preheat ntawm sab carbon nkaus xwb.
