Thermal tshav kub kuj yog hais txog nws lub cev zoo heev thiab txhua yam khoom uas tseem tuaj yeem tuav stainless hlau ntawm qhov kub thiab txias.
Kev cuam tshuam ntawm cov pa roj carbon: Cov pa roj carbon monoxide yog ib qho muaj zog ntawm Austenite stainless hlau thiab stabilizing lub austenite thiab nthuav dav thaj tsam Austenitic.Lub peev xwm ntawm carbon los tsim austenitic yog li 30 npaug ntawm npib tsib xee.Carbon yog qhov sib txawv.Nws tuaj yeem txhim kho lub zog ntawm Austenite stainless hlau los ntawm kev txhim kho-soluble.Cov pa roj carbon kuj tseem tuaj yeem txhim kho qhov kev tiv thaiv thiab kev tiv thaiv corrosion hauv siab tuab chloride (xws li 42% mgCl2 boiling tov).
Txawm li cas los xij, hauv austenitic stainless hlau, carbon feem ntau suav tias yog cov khoom tsis zoo.Qhov no feem ntau yog vim qee qhov xwm txheej (xws li vuam lossis cua sov los ntawm 450 ~ 850 ° C) nyob rau qee qhov xwm txheej hauv stainless hlau).Carbon tuaj yeem ua tau zoo li hlau thiab hlau hauv hlau.Chromium ua ib lub siab chromium CR23C6 carbon compound, uas ua rau cov neeg txom nyem hauv zos chromium, uas txo cov corrosion kuj ntawm steel, tshwj xeeb tshaj yog corrosion kuj ntawm siv lead ua kuj.yog li ntawd.Txij li thaum xyoo 1960, cov tshiab tsim chromium -nickel Austeenian stainless hlau feem ntau yog cov ntsiab lus carbon tsawg dua 0.03% lossis 0.02% ultra-low-carbon hom.Koj tuaj yeem paub tias raws li cov ntsiab lus carbon tsawg, qhov rhiab heev ntawm cov siv lead ua corrosion ntawm steel yog txo.0.02% muaj qhov pom tseeb tshaj plaws.Qee qhov kev sim kuj tau taw qhia tias cov pa roj carbon kuj tuaj yeem ua rau muaj kev nyiam ntawm cov ntsiab lus corrosion ntawm chromium Aozoi stainless hlau.Vim tias muaj kev phom sij ntawm cov pa roj carbon monoxide, tsis yog tsuas yog yuav tsum tau tswj cov ntsiab lus ntawm cov pa roj carbon tsawg li sai tau hauv cov txheej txheem ntawm smelting austenite stainless hlau, tab sis kuj nyob rau hauv cov txheej txheem tom qab cua sov, txias ua thiab kev kho cua sov, tab sis kuj los tiv thaiv lub nto ntawm stainless hlau kom nce carbon nto thiab tsis txhob chromium carbides uas tsis txhob chromium carbides Xaiv.
