Vim li cas Stainless Hlau Tsis Sib Nqus?

Thaum peb xav txog cov hlau tsis muaj steel, ntau ntawm peb tam sim ntawd xav txog cov hlau tsis muaj steel - txhua yam ntawm cov khoom siv hauv chav ua noj, cov khoom siv kho mob, cov khoom siv hluav taws xob tauj dua tshiab, mus rau cov qauv tsim yuav tuaj rau hauv siab. Yog tias koj xav txog nws, koj yuav pom qee yam ua los ntawm stainless hlau yuav luag txhua qhov chaw.

Thaum cov hlau tsis muaj hlau paub txog kev tiv thaiv corrosion, muaj zog, thiab zoo nkauj, ib qho zoo uas feem ntau nug yog nws cov hlau nplaum.

Vim li cas stainless hlau tsis sib nqus?

Koj tuaj yeem nug, yog stainless hlau hlau nplaum? Qhov tseeb yog tias qee qhov stainless hlau yog hlau nplaum thaum lwm tus tsis yog. Koj pom, stainless hlau feem ntau xav tias yog ib hom khoom siv, tab sis nyob rau hauv metallurgy, stainless hlau yeej yog ib pab pawg ntawm cov hlau uas muaj ntau yam zoo thiab cov tshuaj muaj pes tsawg leeg. Qhov tseeb, nws yuav pab tau rau kev xav ntawm stainless hlau raws li cov lus dav dav raws li cov tshuaj muaj pes tsawg leeg ntawm cov hlau.

Yuav ua li cas steel cais raws li stainless hlau?

Cov hlau alloys nrog cov ntsiab lus chromium tsawg kawg yog 10.5% yog nyob rau hauv qeb stainless hlau.

Cov ntsiab lus chromium muab steel tshwj xeeb zoo, nrog rau kev tiv thaiv corrosion zoo heev. Qhov zoo no muab cov hlau tsis muaj hlau tsis muaj xeb. Nws kuj tseem tso cai rau cov hlau kho nws tus kheej tom qab khawb lossis puas lawm - tsis zoo li cov hlau galvanized, uas feem ntau khawb, thiab cov khawb no tuaj yeem ua rau cov hlau thaum kawg corrode.

Dab tsi ua rau ib yam dab tsi sib nqus?

Tab sis rov qab mus rau hlau nplaum. Nyob rau hauv cov ntaub ntawv ntawm steel, seb nws yog magnetic los yog tsis nyob ntawm seb lub microstructure ntawm cov hlau. Basic stainless steels muaj dab tsi hu ua "ferrite" qauv, uas ua rau lawv sib nqus. Nco ntsoov cov ntsiab lus chromium? Nws yog qhov sib ntxiv ntawm chromium uas tsim cov qauv ferritic. Qhov no, nrog rau qhov sib ntxiv ntawm carbon, hardens cov hlau thiab ua rau nws yog martensitic hlau. Stainless hlau txiav cov cuab yeej feem ntau yog martensitic.

Martensitic steels txawv ntawm cov hlau tsis zoo tshaj plaws, hu ua austenitic steels. Hauv austenitic steels, cov ntsiab lus chromium yog siab dua thiab nickel kuj tseem muaj. Nyob rau hauv cov nqe lus ntawm hlau nplaum, nws yog qhov sib ntxiv ntawm npib tsib xee uas ua rau cov hlau tsis muaj hlau nplaum.

Puas yog stainless hlau magnetic?

Raws li kuv tau hais los saum no, qhov no tsis yog tag nrho lossis tsis muaj dab tsi teb. Qee cov hlau tsis muaj hlau yog hlau nplaum thiab qee qhov tsis yog. Qhov kev txiav txim siab rau cov hlau nplaum yog nyob ntawm qhov microstructure ntawm cov hlau. Martensitic stainless hlau (muaj ferritic microstructure) yog hlau nplaum. Austenitic stainless hlau muaj nickel thiab tsis yog hlau nplaum.
