Corrosion Resistance ntawm 316 Stainless hlau nyob rau hauv txawv teb chaws daim ntawv thov

Q1: Dab tsi ntawm corrosion ib puag ncig yog 316 stainless hlau haum rau? A1: Nws yog tsim rau siab -chloride ib puag ncig xws li dej hiav txwv thiab ntsev tsuag, acidic ib puag ncig xws li sulfuric acid thiab phosphoric acid, thiab alkaline ib puag ncig, thiab muaj kev tiv thaiv zoo rau pitting thiab crevice corrosion.

Q2: Ntau npaum li cas yog pitting corrosion kuj ntawm 316 dua 304 stainless hlau? A2: Nyob rau hauv siab -chloride ib puag ncig, pitting corrosion kuj ntawm 316 yog ntau tshaj 3 npaug ntawm 304, thiab nws tus nqi corrosion nyob rau hauv 5% sulfuric acid tov tsuas yog 1/2.7 ntawm 304.

Q3: Puas yog 316 stainless hlau tuaj yeem ua kom xeb tag nrho - tiv taus hauv dej hiav txwv? A3: Tsis yog, txawm hais tias nws yog lub npe hu ua "marine-qib" stainless hlau, nws tsis yog xeb tag nrho- tiv taus hauv dej hiav txwv; corrosion feem ntau tshwm sim hauv qhov khoob lossis qhov chaw ntxhib.

Q4: Qhov txawv ntawm corrosion kuj ntawm 316 thiab 316L stainless hlau yog dab tsi? A4: Lawv qhov kev tiv thaiv corrosion yog qhov zoo ib yam, tab sis 316L muaj cov ntsiab lus qis dua thiab ua haujlwm zoo dua rau intergranular corrosion tom qab vuam, uas yog tsim rau tuab - ntu vuam qhov chaw.

Q5: Yuav ua li cas kuaj qhov corrosion kuj ntawm 316 stainless hlau hauv kev txiav txim txawv teb chaws? A5: Cov txheej txheem feem ntau suav nrog kev ntsuas ntsev ntsev, ntsuas kua qaub, thiab XRF spectrometer kuaj pom cov ntsiab lus molybdenum los xyuas seb cov khoom puas ua tau raws li qhov yuav tsum tau ua.
