1. Vim li cas thiaj tuaj yeem nqus tau hlau sib nqus?
Stainless hlau yog feem ntau tsis - sib nqus lossis tsis muaj zog sib nqus nyob rau hauv ib txwm muaj xwm txheej. Txawm li cas los xij, thaum ua haujlwm txias ua haujlwm xws li kev ncab thiab stamping yog thov rau cov qauv Austenic hauv nws cov qauv siv lead ua yuav hloov mus rau martensite, uas yog sib nqus. Qhov kev hloov pauv no yog qhov hloov pauv ntawm cov qauv sab hauv los ntawm lub zog sab nraud thaum lub sijhawm ua, yog li ua lub stainless hlau nthuav tawm cov khoom sib nqus me me.
2. Yuav ua li cas txog demagnetize thiab debur stainless kav?
Nws yog qhov tsis pom zoo rau cov hlau stainless los ua cov sib nqus thaum ua, thiab burrs yuav tshwm sim ntawm cov txiav sawv. Cov surrs tsis yog cuam tshuam rau cov tsos ntawm cov kav dej stainless hlau tab sis kuj yuav ua kom muaj kev phom sij thaum siv.
Cov kev coj ua hauv kev lag luam yog raws li hauv qab no: Siab {{}} kub quenching. Hom qauv no tuaj yeem hloov cov qauv sab hauv ntawm cov hlau stainless los ntawm cov kub siab, yog li tshem tawm nws cov hlau nplaum. Rau kev deb digring, pickling thiab polishing yog saws. Pickling tuaj yeem tshem tawm cov burrs los ntawm cov tshuaj tiv thaiv tshuaj, thaum lub sij hawm polishing tuaj yeem ua rau saum npoo ntawm cov hlau stainless yeeb nkab thiab dawb ntawm burrs los ntawm kev sib txhuam tshuab kho tshuab.
3. Dab tsi yog cov khoom siv tshwj xeeb ntawm cov hlau stainless?
201 stainless hlau: Nws muaj cov ntsiab lus tsis muaj hnub nyoog qis thiab cov ntsiab lus ntawm manganese. Vim nws tus nqi qis thiab qee yam corrosion tsis kam, nws yog tsim nyog rau ib puag ncig nrog cov khoom lag luam tsis tshua muaj, xws li chav ua noj kom zoo nkauj, xws li cov ntaub ntawv ua kom zoo nkauj thiab cov ntaub ntawv zoo nkauj.
304 Stainless hlau: Nws muaj 18% chromium thiab 8% npib tsib xee, uas muab nws zoo heev corrosion thiab ductility. Cov khoom no ua rau nws siv dav hauv cov liaj teb xws li siab-}}}} Cov khoom siv kho mob, thiab cov khoom siv kho kom zoo nkauj.
316 Stainless Hlau: Ntxiv rau cov chromium thiab npib tsib xee, nws kuj muaj 2% molybdenum. Qhov sib ntxiv ntawm molybdenum tseem ceeb txhim kho nws corrosion tsis kam piv rau 304 stainless hlau. Yog li ntawd, nws feem ntau yog siv nyob rau hauv ntug hiav txwv nrog cov ntsev ntau hauv cov pa, thiab siab}}}}}}}}} devices end devices} end with nrog nruj corrosion tsis kam.
