904L UNS N08904 super duplex yeeb nkab
904L (N08904, 14539) super austenitic stainless hlau muaj 14.0-18.0% chromium, 24.0-26.0% nickel, thiab 4.5% molybdenum. 904L super austenitic stainless hlau yog cov pa roj carbon tsawg, siab nickel, molybdenum austenitic stainless acid-resistant hlau. Nws yog ib yam khoom uas yog los ntawm Fabkis H·S tuam txhab. Nws muaj kev ua haujlwm zoo-passivation muaj peev xwm, zoo heev corrosion kuj, zoo corrosion kuj nyob rau hauv non-oxidizing acids xws li sulfuric acid, acetic acid, formic acid, thiab phosphoric acid, thiab zoo corrosion kuj nyob rau hauv nruab nrab chlorine-muaj xov xwm. Kev ua haujlwm zoo heev rau pitting corrosion, nrog rau kev ua haujlwm zoo rau crevice corrosion thiab kev ntxhov siab corrosion. Nws yog haum rau sulfuric acid ntawm ntau yam concentrations hauv qab no 70 degree. Nws tuaj yeem tiv taus acetic acid ntawm txhua qhov concentration thiab kub nyob rau hauv lub siab ib txwm muaj, thiab muaj kev tiv thaiv corrosion zoo hauv cov kua qaub sib xyaw ntawm formic acid thiab acetic acid.
Super austenitic stainless hlau 904L (00Cr20Ni25Mo4.5Cu; UNS: N08904; EN: 1.4539) yog cov hlau tsis muaj hlau austenitic uas muaj cov ntsiab lus carbon tsawg. Nws muaj zoo corrosion kuj nyob rau hauv dilute sulfuric acid thiab yog tsim rau corrosive tej yam kev mob. Tsim los rau ib puag ncig hnyav. Nws muaj cov ntsiab lus siab chromium thiab cov ntsiab lus nickel txaus. Qhov sib ntxiv ntawm tooj liab ua rau nws cov kua qaub-resistant, tshwj xeeb tshaj yog tiv taus chloride gap corrosion thiab kev nyuaj siab corrosion cracking. Nws tsis yooj yim rau corrosion me ntsis thiab kab nrib pleb, thiab yog resistant rau me ntsis. Nws cov corrosion kuj yog me ntsis zoo dua li lwm hom hlau, nws muaj kev ua tau zoo thiab weldability, thiab tuaj yeem siv rau hauv cov hlab ntsha siab.
