431 Stainless Hlau Round Bar

431 stainless hlau yog ib hom martensitic stainless hlau nrog cov ntsiab lus chromium siab thiab nruab nrab cov ntsiab lus nickel. Nws yog feem ntau siv nyob rau hauv daim ntawv thov uas yuav tsum tau zoo corrosion kuj, siab toughness, thiab siab tensile zog.

Ib puag ncig bar ua los ntawm 431 stainless hlau yuav yog ib tug cylindrical pas nrig-zoo li tus hlau bar nrog ib txoj kab uas hla ntsuas nyob rau hauv lub bar qhov widest point. Qhov loj thiab ntev ntawm lub bar tuaj yeem sib txawv nyob ntawm daim ntawv thov, tab sis nws yog feem ntau siv hauv kev tsim kho, kev tsim khoom, thiab kev lag luam engineering.

431 stainless hlau puag ncig bar tuaj yeem ua tshuab, welded, thiab kho cua sov los txhim kho nws cov khoom. Nws yog feem ntau siv rau hauv daim ntawv thov xws li twj tso kua mis, bolts, ceev, zog, thiab li qub. Lub zog siab thiab corrosion kuj ntawm 431 stainless hlau ua rau nws haum rau siv nyob rau hauv hnyav ib puag ncig xws li marine thiab tshuaj ua lag luam.

431 stainless hlau yog martensitic stainless hlau nrog siab hardness thiab zoo corrosion kuj. Lub hardness ntawm 431 stainless hlau nyob ntawm qhov kev kho cua sov thiab qhov kawg tempering kub.

Lub hardness ntau yam rau 431 stainless hlau nyob rau hauv lub annealed mob yog 217-248 Brinell hardness (HB), thaum lub hardness nyob rau hauv lub tempered mob tuaj yeem nyob ntawm 277-440 HB.

Nyob rau hauv lub siab hardened thiab tempered mob, lub hardness yuav siab li 50-52 HRC (Rockwell hardness scale C). Txawm li cas los xij, nws tsim nyog sau cia tias qhov tseeb hardness yuav nyob ntawm cov txheej txheem kev kho cua sov tshwj xeeb siv.

431 stainless hlau magnetic zog

431 stainless hlau yog martensitic stainless hlau uas muaj corrosion kuj zoo thiab siab tensile zog. Nws kuj yog magnetic nyob rau hauv cov xwm, uas txhais tau hais tias nws yuav attracted los ntawm ib tug hlau nplaum. Cov khoom sib nqus ntawm 431 stainless hlau yog vim nws cov microstructure, uas feem ntau yog tsim los ntawm ferrite thiab martensite.

Ferrite yog cov khoom sib nqus uas muaj hlau thiab muaj lub cev-centered cubic (BCC) siv lead ua qauv. Nws yog hom hlau ntau tshaj plaws thiab yog sib nqus ntawm chav tsev kub. Martensite, ntawm qhov tod tes, yog theem tsis sib npaug uas tshwm sim thaum austenitic stainless hlau yog txias txias los ntawm qhov kub siab.

Nyob rau hauv 431 stainless hlau, muaj martensite thiab ferrite nyob rau hauv lub microstructure pab rau nws cov khoom sib nqus. Tus nqi ntawm martensite hauv cov hlau tuaj yeem cuam tshuam rau qib ntawm cov hlau nplaum, nrog rau ntau dua ntawm martensite ua rau muaj zog sib nqus.

Zuag qhia tag nrho, cov khoom sib nqus ntawm 431 stainless hlau ua rau nws muaj txiaj ntsig zoo rau cov ntawv thov uas xav tau cov khoom sib nqus, xws li hauv qee yam khoom siv hluav taws xob, sib nqus bearings, thiab cov tshuab tsav sib nqus.
