gnee cev team
1.4539 stainless hlau alloy steel yeeb nkabmuaj cov yam ntxwv zoo ntawm kev ua haujlwm siab alloy. Cov khoom muaj xws li kev ua haujlwm siab corrosion, kub tsis kam, siab zog thiab lwm yam khoom tshwj xeeb xws li non-magnetizability. Cov alloys no yog siv nyob rau hauv hnyav ib puag ncig nyob rau hauv hnyav tej yam kev mob nyob rau hauv advanced technologies xws li desalination, atomic zog, semiconductors, solar cells thiab roj hlwb.
1.4539 stainless hlau yeeb nkab yog austenitic stainless hlau nrog zoo corrosion kuj piv rau 316L steel yeeb nkab. Vim tias qhov sib ntxiv ntawm Cu (1.5%), cov khoom muaj kev tiv thaiv zoo heev tiv thaiv kev txo cov acids xws li sulfuric acid thiab phosphoric acid. Nws yog siv nyob rau hauv tshuaj nroj tsuag thiab ntau yam ntawm lwm yam kev siv.
Cov tshuaj muaj pes tsawg leeg ntawm 1.4539 stainless hlau round yeeb nkab feem ntau muaj 23% chromium, 19% nickel, 5% molybdenum thiab 2% tooj liab. Nws kuj muaj me me ntawm silicon, manganese, phosphorus thiab lwm yam khoom. Qhov tsim nyog feem ntawm cov ntsiab lus no tuaj yeem ua rau 1.4539 stainless hlau acid-resistant yeeb nkab muaj corrosion kuj zoo heev thiab muaj peev xwm tiv taus corrosion los ntawm ntau cov kua qaub thiab muaj zog alkali xov xwm, tshwj xeeb tshaj yog cov xov xwm corrosive hauv qee qhov chaw marine, xws li dej hiav txwv, magnesium chloride, thiab lwm yam. Nyob rau tib lub sijhawm, nws muaj qhov kub thiab txias thiab tuaj yeem siv rau qhov kub siab dua yam tsis muaj kev puas tsuaj.
