Ntawm ntau pawg ntawm stainless hlau, Martensitic Stainless hlau sawv tawm rau nws cov khoom siv kho tshuab zoo heev thiab kho tau qhov nyuaj, ua rau nws siv dav hauv kev lag luam. Qhov tsab xov xwm SEO-optimized no muab cov kev tshaj lij ntawm nws cov kev kho cua sov, cov txheej txheem raug, thiab cov txiaj ntsig zoo los pab cov kws tshaj lij kev muag khoom, cov kws tsim khoom, thiab cov tuam txhab tsim khoom kom nkag siab txog cov khoom tseem ceeb no.
Martensitic Stainless hlau yog dab tsi?
Martensitic stainless hlau yog ib hom kub-kho stainless hlau uas ua tiav lub zog siab thiab hardness. Cov qhab nia raug suav nrogAISI 410, 420, thiab 440C. Cov hlau no feem ntau yog alloyed nrog chromium (11.5% -18%) thiab kuj tseem muaj cov pa roj carbon, npib tsib xee, molybdenum, thiab lwm yam.
Kev kho cua sov
Kev ua tau zoo ntawm martensitic stainless hlau feem ntau nyob ntawm nws cov kev kho cua sov, uas feem ntau cuam tshuam nrog annealing, quenching, thiab tempering.
| Txheej txheem txheej txheem | Qhov kub thiab txias (°C) | Nta & Lub Hom Phiaj |
| Annealing | 800-900 Nws | softens tus qauv, txhim kho kev ua haujlwm, txo cov kev ntxhov siab sab hauv |
| Quenching | 950-1050 : kuv | Tsim cov qauv martensitic, nce hardness thiab lub zog |
| Tempering | 150-550 | Kho hardness thiab toughness, txo quenching kev nyuaj siab |
Kev kho cua sov yam ntxwv
1.High Hardening Peev Xwm:Ua tiav siab hardness (HRC 45-58) los ntawm kev tsim martensite thaum quenching.
2.Excellent Tempering Control:Cov khoom siv kho tshuab tuaj yeem raug kho kom zoo los ntawm kev kho qhov kub thiab txias.
3.Moderate Dimensional Stability:Qee qhov kev cuam tshuam tuaj yeem tshwm sim thaum kho cua sov, ua rau nws tsim nyog rau cov ntawv thov uas tsis tshua muaj kev sib txawv ntawm qhov ntev.
4.Moderate Corrosion Resistance:Vim muaj cov ntsiab lus siab dua carbon, corrosion kuj yog qis dua austenitic hom tab sis superior rau carbon steel.
Tej kev siv
Ua tsaug rau lawv lub zog tunable thiab hardness, martensitic stainless hlau feem ntau siv hauv:
• Cov cuab yeej txiav: txiab, cov hniav phais, cov cuab yeej txiav
• Valves thiab Shafts: Zoo tagnrho rau cov khoom siv hnyav thiab hnyav hnyav
• Cov Khoom Siv Petrochemical: Rau cov khoom uas xav tau lub zog tab sis tsis raug corrosion hnyav
Xaus
Martensitic stainless hlau yog cov khoom siv zoo tshaj plaws rau kev siv lub zog siab vim nws qhov ua tau zoo thaum kho cua sov kom zoo. Nws yog ib qho tseem ceeb uas yuav tau txheeb xyuas qhov kawg daim ntawv thov kom meej thiab xaiv qhov raug tempering kub kom sib npaug hardness thiab toughness.
