Xaiv qhov raug vuam siv tau rau 304 stainless hlau yog qhov tseem ceeb rau kev tiv thaiv corrosion, txhua yam muaj zog, thiab weld ntev. Nyob rau hauv kev lag luam fabrication, marine engineering, khoom noj khoom haus, thiab tshuaj piping, tsis ncaj ncees lawm muab tub lim hlau yuav ua rau rhiab heev, tawg, los yog ntxov ntxov corrosion tsis ua hauj lwm.
Raws li ib tugstainless hlau manufacturers, Sxthsteel ua haujlwm ze nrog fabrication engineers thiab welding teams los xyuas kom meej cov ntaub ntawv compatibility nyob rau hauv cov qib, txheej txheem, thiab ib puag ncig.
Phau ntawv qhia no piav qhia raws nraim li cas vuam hlau siv rau 304 stainless hlau, vim li cas nws tseem ceeb, thiab yuav ua li cas xaiv qhov kev xaiv zoo rau kev siv sib txawv.
Qhov zoo tshaj plaws Vuam Hlau rau 304 Stainless Hlau
Qhov feem ntau pom zoo vuam hlau rau 304 stainless hlau yog:
ER308L (feem ntau tus qauv xaiv)
ER308LSi (zoo dua fluidity thiab hlaws zoo li)
ER308H (rau siab -cov ntawv thov kev pabcuam kub)
Hauv qee kis tshwj xeeb:
TSI 309Lyog siv rau vuam 304 rau cov hlau tsis sib xws (xws li carbon steel)
👉 Kev pom zoo tus qauv kev lag luam:
Rau feem ntau fabrication ua hauj lwm nrog 304 stainless hlau,ER308L yog qhov kev xaiv ua ntej thiab nyab xeeb tshaj plaws.
Vim li cas ER308L Yog Qhov Kev Xaiv Zoo Tshaj?
304 stainless hlau yog qib austenitic nrog kwv yees li 18% chromium thiab 8% npib tsib xee. ER308L yog tshuaj lom neeg tsim los ua kom haum rau qhov muaj pes tsawg leeg.
Cov laj thawj tseem ceeb ER308L yog siv:
Matches corrosion kuj ntawm 304 puag hlau
Tsawg carbon cov ntsiab lus txo cov carbide nag lossis daus (txhim kho weld durability)
Stable austenitic weld qauv
Zoo tawg tsis kam nyob rau hauv ntau- hla vuam
Qhov twg nws yog feem ntau siv:
Khoom noj khoom haus ua tank
Cov kav dej mis
Cov cuab yeej siv tshuaj
Architectural stainless hlau qauv
Kev kho dej
Thaum twg koj yuav tsum tsis txhob siv ER308L?
Txawm hais tias ER308L yog lub neej ntawd, nws tsis yog universal.
Xav txog lwm txoj hauv kev thaum:
✔ Welding dissimilar hlau (304 rau carbon steel)
→ SivTSI 309L
✔ Kev kub ceev caij tsheb kauj vab lossis kev pabcuam kub heev
→ Xav txogER308H lossis ER309H
✔ Ntxiv cov hlaws zoo li yuav tsum tau (automated TIG / MIG)
→ SivER 308 LSI

Tswv yim Vuam Qhia rau 304 Stainless Hlau
MIG Vuam:
Siv ER308L xaim nrog Argon lossis Ar/CO₂ sib xyaw cov roj tiv thaiv
Khaws cov cua kub qis kom tsis txhob cuam tshuam
TIG Welding:
Siv ER308L muab tub lim nrog ntshiab Argon shielding
Zoo tagnrho rau nyias- phab ntsa tubing thiab cov kav dej huv
Common yuam kev kom zam:
Siv carbon steel muab tub lim (ua rau corrosion tsis ua hauj lwm)
Overheating (ua rau carbide nag lossis daus)
Tsis quav ntsej txog kev huv ntawm lub hauv paus hlau
