3. Tshuaj lom neeg Corrosion kuj
Feem ntau hais lus, 304 stainless hlau thiab 316 stainless hlau muaj qhov sib txawv me me ntawm kev siv tshuaj lom neeg ua haujlwm, tab sis lawv txawv hauv qee cov xov xwm tshwj xeeb.
Pib tsim stainless hlau 304 yog qhov rhiab rau xeb ntsiab lus hauv qee yam. Ntxiv 2-3% molybdenum tuaj yeem txo qhov kev nkag siab no, uas ua rau 316. Tsis tas li ntawd, cov molybdenum no tseem tuaj yeem txo qhov xeb ntawm qee cov kua qaub thermoorganic.
4.Txoj qis hlau Stainless
Kev tiv thaiv corrosion ntawm austenitic stainless hlau cuam tshuam txog chromium oxide tiv thaiv txheej tsim nyob rau saum npoo hlau. Yog tias cov khoom siv raug kub rau 450 ℃ -900 ℃, cov qauv ntawm cov khoom yuav hloov thiab chromium carbide yuav ua raws ntug kev siv lead ua. Yog li, txheej txheej tiv thaiv ntawm chromium oxide tsis tuaj yeem tsim nyob ntawm ntug ntawm cov siv lead ua, uas ua rau txo qis ntawm corrosion tsis kam.
Yog li 304L stainless hlau thiab 316L stainless hlau tau tsim los tiv cov tshuaj tiv thaiv no. Cov pa roj carbon ntsiab lus ntawm 304L stainless hlau thiab 316L steel hlau qis dua, vim tias cov pa roj carbon ntsiab lus tsawg dua, yog li yuav tsis muaj chromium carbide.
