Muaj ntau qib stainless hlau hauv kev faib tawm, feem ntau siv yog 304, 310 lossis 316 thiab 316L, ces tib yam yog 316 stainless hlau flange qab L yog xav li cas? Qhov tseeb, nws yooj yim heev. Ob leeg 316 thiab 316L yog stainless hlau flanges uas muaj molybdenum, thaum cov ntsiab lus ntawm molybdenum nyob rau hauv 316L stainless hlau flanges yog me ntsis siab dua li ntawm 316 stainless hlau. Stainless hlau Nrog molybdenum ntxiv rau lub flange, tag nrho cov kev ua tau zoo zoo dua li 304 lossis 310 stainless hlau. Feem ntau 316 stainless hlau yog haum rau siv nyob rau hauv sulfuric acid concentration hauv qab no 15% los yog siab tshaj 85% Yog li nws tsis kam mus rau chloride yaig muaj zog heev, thiab feem ntau yog siv nyob rau hauv Marine ib puag ncig.

Cov ntsiab lus carbon nyob rau hauv 316L stainless hlau tsuas yog 0.03, uas yog heev haum rau vuam qhov chaw uas tsis tuaj yeem annealed thiab xav tau muaj zog corrosion kuj.
Nyob rau hauv lwm yam lus, 316 stainless hlau flanges thiab 316L stainless hlau flanges yog ntau corrosion resistant tshaj 304 los yog 310 stainless hlau flanges. Tab sis kuj tuaj yeem tiv taus dej hiav txwv thiab ua haujlwm Atmospheric yaig.
316 stainless hlau flange muaj kev vuam zoo. Yuav siv tau rau txhua txoj kev vuam, hauv cov txheej txheem vuam tuaj yeem ua raws li lub hom phiaj ntawm 316CB, 316L lossis 309CB yog siv los ua tus muab tub lim rau vuam. Lub 316 stainless hlau flange yuav tsum tau kho kom zoo tom qab vuam kom tau zoo dua corrosion kuj.
