309L yog stainless hlau vuam hlau feem ntau siv rau vuam sib txawv ntawm cov hlau sib txuas ntawm stainless hlau thiab carbon hlau los yog qis- hlau alloy, nrog rau siv los ua ib txheej tsis nyob rau hauv cov ntaub ntawv cladding. Nws cov ntsiab lus carbon tsawg (feem ntau qis dua 0.03%) pab txo qis carbide nag lossis daus, txhim kho kev tiv thaiv intergranular corrosion, thiab ua rau nws haum rau siab - kub thiab corrosive ib puag ncig.
Cov ntawv thov ib txwm muaj xws li:
- Cov hlau tsis sib xws: Piv txwv, koom nrog 304 stainless hlau nrog carbon steel, feem ntau siv hauv petrochemical, khoom noj khoom haus, thiab kev tsim cov hlab ntsha.
- Clad welding: Thaum tso cov hlau tsis muaj steel cladding txheej mus rau carbon steel substrate, nws ua hauj lwm raws li ib tug kev hloov txheej los xyuas kom meej compatibility ntawm cov khoom ntawm ob cov ntaub ntawv.
- Vuam ntawm cov hlau tsis zoo sib xws: Siv rau vuam castings lossis forgings ntawm 309 stainless hlau, los yog kho siab - cov cuab yeej kub (xws li cov khoom siv rauv).
Txheej txheem Compatibility:309L vuam hlau txhawb ntau txoj kev vuam xws li TIG (Tungsten Inert Gas Vuam), MIG (Hlau Inert Gas Vuam), thiab FCAW (Fluid-Cored Wire Vuam), haum rau txhua qhov - txoj haujlwm vuam. Feem ntau siv shielding gases yog cov ntshiab argon los yog sib tov ntawm argon thiab ib tug me me ntawm carbon dioxide / oxygen.
Daim ntawv thov kev lag luam:Feem ntau siv nyob rau hauv cov teb uas yuav tsum tau muaj corrosion kuj thiab siab -kub kev ua tau zoo, xws li nuclear zog, shipbuilding, hluavtaws fiber ntau, thiab nuclear reactor Cheebtsam.
