Khoom Description
Qhia ntau qib ntawm austenitic stainless hlau thiab lawv cov tshuaj muaj pes tsawg leeg uas yuav tsum tau ua.
Cov qib muaj xws li 304, 304L, 316, 316L, thiab lwm yam.
Cov ntsiab lus ntawm ntau lub ntsiab lus ua lub luag haujlwm tseem ceeb hauv cov khoom ntawm ASTM A409 Welded Loj Diameter Stainless Hlau Yeeb Nkab, xws li corrosion kuj, lub zog, thiab kev ua haujlwm.
Piv txwv li, hauv qib 304, cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.08%, cov ntsiab lus chromium yog 18.00 - 20.00%, thiab cov ntsiab lus nickel yog 8.00 - 11.00%. Hauv qib 304L, cov ntsiab lus carbon tseem qis dua, Tsawg dua lossis sib npaug li 0.035%, thiab cov ntsiab lus ntawm lwm cov ntsiab lus kuj txawv me ntsis. Cov ntsiab lus qis dua txo cov carbide nag lossis daus thaum lub sijhawm vuam thiab txhim kho kev tiv thaiv intergranular corrosion, ua rau nws tsim nyog rau cov cheeb tsam uas muaj kev tiv thaiv corrosion siab.
