Qhov sib txawv ntawm 316 stainless hlau thiab 316L stainless hlau
Qhov sib txawv ntawm 316 stainless hlau thiab 316L stainless hlau
Qhov sib txawv tseem ceeb ntawm 316 thiab 316L stainless hlau nyob hauv lawv cov ntsiab lus carbon: 316L ("tsawg carbon") muaj cov ntsiab lus siab tshaj plaws ntawm 0.03%, thaum tus qauv 316 tuaj yeem muaj cov ntsiab lus siab tshaj plaws ntawm 0.08%. Vim tias cov ntsiab lus qis dua ntawm 316L tiv thaiv carbide nag lossis daus (weld corrosion) thiab tswj kom zoo dua corrosion kuj nyob rau hauv tshav kub- cuam tshuam cheeb tsam, nws yog tsim nyog rau vuam daim ntaub ntawv. Ob leeg muaj kev tiv thaiv corrosion zoo heev vim muaj cov molybdenum, tab sis 316L yog qhov zoo dua rau qhov hnyav -cov haujlwm vuam thiab hnyav ib puag ncig, txawm hais tias 316 muaj zog dua me ntsis thiab cov nqi zoo sib xws.
Cov hlau nplaum puas tuaj yeem nyiam 316L stainless hlau?
Vim nws cov ntsiab lus siab nickel, 316 stainless hlau yog suav tias yog "tsawg kawg magnetic" stainless hlau. Txawm li cas los xij, 316 stainless hlau cov khoom lag luam uas tau dhau los ua vuam lossis tshuab ua haujlwm yuav muaj cov hlau nplaum txaus los ua kom pom qhov ntxim nyiam thaum coj los ze rau cov hlau nplaum.
Dab tsi yog 316 stainless hlau?
316 stainless hlau yog chromium -nickel{2}}raws li alloy nrog ntau yam khoom uas txhim kho nws cov corrosion kuj. Qhov sib ntxiv ntawm molybdenum ntxiv txhim kho nws cov corrosion kuj.
Dab tsi yog 316L stainless hlau?
316L stainless hlau muaj cov ntsiab lus qis dua li 316 stainless hlau. Txawm li cas los xij, qhov no yog vim qhov no alloy xav tau kev kho cua sov thaum lub sij hawm tsim cov khoom siv. Cov hlau no muaj cov qauv zoo tshaj plaws carbon nag lossis daus thiab feem ntau siv rau vuam.
