gnee cev team
1.4432 stainless hlau yeeb nkabfeem ntau hu ua qib 316L. Qhov no stainless hlau yog ib tug tsawg carbon austenitic stainless hlau tshwj xeeb tshaj yog haum rau vuam daim ntaub ntawv uas susceptibility rau intergranular corrosion yog ib qho kev txhawj xeeb. Tus qauv lub npe rau cov khoom no feem ntau yog ASTM A312 TP316L.
1.4432 alloy tube yog tsim los ntawm cov feem ntau ntawm chromium, npib tsib xee thiab molybdenum cov ntsiab lus thiab feem ntau yog siv los tsim cov cuab yeej tseem ceeb hauv kev lag luam tshuaj, nkoj tsim, roj av, tshuaj thiab khoom noj khoom haus. Thaum siv cov yeeb nkab alloy no, xaiv cov txheej txheem ua haujlwm zoo yog qhov tseem ceeb los xyuas kom meej tias nws qhov kev ua tau zoo thiab corrosion kuj.
Feem ntau, 1.4432 stainless hlau hollow raj yog high-alloy stainless hlau nrog zoo corrosion kuj thiab zoo forging kev ua tau zoo, thiab tuaj yeem yooj yim forged rau hauv ntau yam duab. Hauv daim ntawv thov, xaiv cov txheej txheem tsim nyog raws li cov kev xav tau tshwj xeeb yog tus yuam sij kom ntseeg tau nws qhov kev ua tau zoo thiab kev tiv thaiv corrosion.
