316 thiab 440 zwm rau lub aristocracy ntawm cov khoom siv stainless hlau, nrog zoo xeb tsis kam thiab muaj zog corrosion kuj, thiab tus nqi nce nrog tus nqi. Hauv qab no Cov Pob Hlau Hlau Condar hauv qab no qhia txog ob qho kev nthuav dav:
1.316 stainless hlau khoom—Tom qab 304, nws yog qhov thib ob feem ntau siv steel qib. Nws yog tsuas yog siv hauv kev lag luam khoom noj khoom haus thiab phais khoom siv. Qhov sib ntxiv ntawm molybdenum ua rau nws tshwj xeeb xeb-tiv thaiv cov qauv. Vim tias nws muaj qhov cuam tshuam zoo rau chloride corrosion dua 304, nws kuj yog siv ua "nkoj hlau". SS316 feem ntau yog siv hauv cov khoom siv roj thim rov qab, cov khoom siv kho mob, cov khoom siv dhia, thiab lwm yam.
2.440 pawg hlau stainless—High-lub zog txiav cuab tam steel nrog me ntsis siab dua cov ntsiab lus carbon. Tom qab kho cov cua sov kom zoo, cov txiaj ntsig ntau dua tuaj yeem tau txais. Lub zog ua tau ncav 58HRC, uas yog ntawm qhov nyuaj tshaj plaws steel hlau. Ua ke qhov zoo ntawm stainless hlau thiab kev coj tus kheej steel, nws yog hu ua tshwj xeeb steel. Feem ntau cov ntawv thov piv txwv yog "chais plaub". Muaj peb tus qauv siv feem ntau: 440A, 440B, 440C, thiab 440F (hom ua tau yooj yim).
