1. Piv nrog rau 904L, S32750 dual-theem steel muaj zog corrosion kuj mus dilute sulfuric acid tov nrog chloride ions.
904L yog austenitic alloy tshwj xeeb uas tsim los tiv thaiv corrosion ntawm ntshiab sulfuric acid.
Qhov siab dua chromium thiab molybdenum cov ntsiab lus ntawm S32750 dual-theem steel ua rau nws tiv taus tag nrho corrosion ntawm cov organic acids xws li kua qaub thiab acetic acid.
S32750 duplex steel kuj muaj zog corrosion kuj rau inorganic acids, tshwj xeeb tshaj yog cov uas muaj chlorides.
Qib 316L tsis tuaj yeem siv rau hauv hydrochloric acid ib puag ncig uas nws yuav raug rau hauv zos lossis thoob ntiaj teb corrosion.
S32750 dual-theem steel tuaj yeem siv rau hauv qhov chaw dilute hydrochloric acid ib puag ncig, muaj zog tiv thaiv qhov chaw puas thiab tawg muaj peev xwm.
2. Intercrystalline corrosion S32750 dual-theem steel muaj cov pa roj carbon tsawg dua, uas txo qhov kev pheej hmoo ntawm intercrystalline carbide nag lossis daus thaum kho cua sov.Yog li ntawd, cov hlau no muaj zog heev rau carbon-txog intercrystalline corrosion.
3. Kev nyuaj siab corrosion cracking: vim nws cov ntsiab lus alloy siab, corrosion kuj thiab lub zog ntawm S32750 dual-theem steel zoo dua li ntawm 2205.
S32750 dual-theem steel sib xyaw qauv ua rau nws muaj peev xwm tiv taus kev ntxhov siab corrosion tawg.
4, corrosion thiab corrosion: muaj ntau txoj hauv kev los ntsuam xyuas qhov corrosion kuj ntawm steel khoom nyob rau hauv cov tshuaj uas muaj chloride.Qhov ntsuas kub tseem ceeb rau corrosion thiab corrosion ntawm high-performance stainless hlau ntawm 1M sodium chloride tov yog teev.
Ntau yam kev sim tau pom tias S32750 dual-theem steel muaj kev tiv thaiv corrosion zoo heev.
5, tawg corrosion: kab nrib pleb nyob rau hauv lub tsev thiab lwm yam yog yuav luag inevitable, uas ua rau stainless hlau muaj kev cuam tshuam corrosion nyob rau hauv lub chloride ib puag ncig.2507 dual - theem steel muaj ib tug muaj zog tiv thaiv - tawg corrosion muaj peev xwm.
