Hom Martensitic Stainless Hlau
410 stainless hlau
410 stainless hlau yog feem ntau hom martensitic stainless hlau thiab yog lub npe hu ua general-purpose martensitic steel. Nws yog feem ntau pom nyob rau hauv cov mob annealed thiab muaj qhov tsawg kawg nkaus tensile lub zog ntawm 110, 000 psi. Tus nqi hardness tuaj yeem sib txawv nyob ntawm qhov kev kho cua sov siv. 410 stainless hlau yog siv rau fasteners, nrog rau cov txiv ntseej thiab bolts, nrog rau, li qub, pistons, pob bearings, impellers, turbine hniav, springs, pins, thiab micrometers.
440 stainless hlau
440 stainless hlau muaj qhov nyuaj tshaj plaws thaum piv rau 410 thiab 420 steel. Txawm li cas los xij, qhov ntawd los ntawm tus nqi ntawm kev txo qis formability. Qhov siab hardness no yog nrhiav tom qab rau kev tsim cov hniav, vim nws ua rau cov hniav nyob twj ywm sharper ntev dua. 440 steel yog siv los ua cov hniav, hauv cutlery, cov cuab yeej phais, thiab cov kabmob.
420 stainless hlau
420 stainless hlau yog cov hlau tsis muaj roj carbon tsawg, uas tuaj yeem muaj ntau yam hardness qhov tseem ceeb nyob ntawm nws cov kev kho cua sov. Thaum tshav kub-kho thiab txias-kuav los tiag, 420 stainless hlau tuaj yeem xav kom ua tiav lub zog tensile yam tsawg kawg nkaus ntawm 120,000 psi. 420 steel muaj cov ntawv thov hauv cov fasteners, tshuab qhov chaw, cov cuab yeej phais, thiab phom.
High-carbon martensitic hlau
Qhov feem pua ntawm cov pa roj carbon ntau hauv cov pa roj carbon martensitic stainless hlau yog nruab nrab ntawm 0.61% thiab 1.50% cov pa roj carbon ntau ntawm cov hlau ua rau nws muaj zog los ntawm kev cuam tshuam cov molecular bonds ntawm microstructure. Lub downside ntawm muaj cov ntsiab lus siab carbon yog tias nws ua rau cov hlau ntau nkig thiab txo nws lub peev xwm los welded thiab tsim. Vim nws cov hardness siab thiab lub zog, high-carbon steel yog siv rau riam, pob bearings, pwm, thiab tuag.
Tsawg-carbon martensitic hlau
Cov pa roj carbon muaj pes tsawg leeg ntawm cov pa roj carbon tsawg martensitic stainless hlau yog 0.05–0.25%.

Cov txheej txheem ntau lawm ntawm Martensitic Stainless hlau
Martensite stainless hlau muaj siab hardenability thiab tuaj yeem ua kom tawv los ntawm huab cua txias.Yog li ntawd, kev ntsuas yuav tsum tau coj los tiv thaiv kev tawg ntawm cov hlau forged martensite, tshwj xeeb tshaj yog nyob rau hauv cov pa roj carbon siab. 593 degree c.Cracking tshwm sim yog dej yog txau ncaj qha rau ntawm forging, raws li nws ua thaum tuag yog txias. Feem ntau, martensitic stainless hlau forgings yog tempered tom qab forging los txo cov hardness ntawm cov hlau kom nws thiaj li ua tiav.
Xaiv martensite stainless hlau qhov siab tshaj plaws forging kub kom qis tshaj qhov kub ntau lawm, txwv tsis pub yooj yim rau tawg.Nws feem ntau yog tsim ntawm qhov kub thiab txias ntawm 1093 degree thiab 1260 degree .Tshwj xeeb yuav tsum tau saib xyuas kom tsis txhob siab tshaj qhov kub ntawm lub sijhawm forging kom tsis txhob muaj cua sov hauv zos. vim yog cov hlau ceev ceev.Ntxiv mus, decarbonization decarbonization txhawb kev tsim ferrite thiab yog li yuav tsum tau txwv.
Nrog rau qhov nce ntawm chromium cov ntsiab lus, ferrite tsim kub txo, thiab me me ntawm ferrite ho txo nws cov ductility.Raws li ferrite nce mus rau ntau tshaj 15%, malleability maj mam nce mus txog rau thaum cov ntaub so ntswg hloov mus rau hauv ferrite.Qhov kawg forging kub yog raug. rau allotropic transformation (lub allotropic transformation pib nyob ib ncig ntawm 816 degree c), thiab cov hlau feem ntau yog nres ntawm 927 degree c vim nws nyuaj rau pwm thaum kub tsawg dhau.
Ntxiv cov sulfur lossis antimony rau y12crl3(416) steel tuaj yeem txhim kho nws cov machinability, tab sis cov ntsiab lus no tuaj yeem ua rau muaj teeb meem forging, tshwj xeeb tshaj yog tias lawv tsim cov phaj-hom qauv.Tab sis los ntawm kev kho qhov kub thiab txias thiab txheej txheem tuaj yeem raug tshem tawm.Yog ntxiv sulfur. , xws li tawg tsis tuaj yeem raug tshem tawm.Los ntawm qhov kev pom no, nws yog qhov zoo dua los ntxiv selenium.
Martensitic stainless hlau yuav tsum zam qhov tsim ntawm s-ferrite nyob rau hauv lub forging cua sov txheej txheem, vim hais tias cov tsos ntawm ferrite yuav ua rau cov kab nrib pleb nyob rau hauv cov txheej txheem forging. Tsis tas li ntawd, tsis txhob overheating los ntawm stainless hlau forgings.Qhov decarburization ntawm forgings thaum lub sij hawm cua sov mas txhawb. Qhov tsim ntawm ferrite, yog li lub decarburization ntawm forgings nto yog minimized.Yog tsis muaj qhov tshwj xeeb yuav tsum tau rau qhov kawg hluav taws deformation ntawm martensitic stainless hlau.Qhov steel tawg yooj yim tom qab forging.Qhov laj thawj yog tias muaj martensite thiab carbide qauv tom qab cua txias, thiab cov kev ntxhov siab sab hauv yog zoo heev.Yog li ntawd, tom qab forging txias, yuav tsum tau nqa tawm maj mam, feem ntau nyob rau hauv 200 degree sandpit los yog slag qhov chaw, tom qab lub forging raug tshem tawm, yuav tsum tau nqa tawm nyob rau hauv lub sij hawm isothermal annealing, tiv thaiv cracking.
Martensitic stainless hlau, tshwj xeeb tshaj yog hom crl3, yog pheej yig, dav siv nyob rau hauv corrosive media (xws li dej vapor) thiab yuav tsum tau ntau dua mechanical zog.Lub 12crl3 steel yog ib tug semi-martensitic stainless hlau nrog ferrite qauv ntxiv rau martensitic qauv.
Kev kho cua sov ntawm Martensitic Stainless Hlau
Kev kho cua sov ntawm martensitic stainless hlau ua tiav peb txheej txheem, xws li austenitising, quenching thiab tempering.
Austenitising
Austenitising suav nrog cua sov cov hlau mus rau qhov kub ntawm 980 degree c thiab 1050 degree c, uas tso cov hlau rau hauv nws theem austenitic nrog fcc siv lead ua qauv.
Quenching
Quenching tshwm sim thaum cov hlau yog txias txias hauv huab cua los yog lwm yam xov xwm, xws li roj, uas hloov feem ntau ntawm cov austenite mus rau hauv martensite nrog ib tug tshiab bcc crystal qauv. Qhov tshiab tsim martensite no nyuaj heev piv rau austenite.
Tempering
Tempering yog thaum lub zog mechanical ntawm cov hlau yog customized. Nws yog cov txheej txheem ntau dua li austenitising thiab quenching. Quenched martensite tsis npaj rau feem ntau daim ntawv thov, thiab yog li, yuav tsum tau kho cua sov ntxiv. Tempering muaj cua sov cov hlau mus txog 500 degree c thiab tswj nws ntawm qhov kub thiab txias ua ntej nws txias hauv huab cua. Tempering yuav tsum tau ua nyob rau ntawm qhov kub thiab txias ntau yam raws li lawv cuam tshuam cov khoom siv ntawm cov hlau tiav, xws li lub zog tensile, elongation thiab cuam tshuam tsis kam.
Dab tsi yog Mechanical Properties ntawm Martensitic Stainless Hlau
Hardness
Martensitic stainless hlau yog lub npe hu rau nws cov hardness siab, ib qho kev ntsuas ntawm nws tsis kam mus indentation los yog khawb. Lub hardness ntawm cov hlau no txawv nyob ntawm seb cov qib tshwj xeeb thiab cov txheej txheem kho cua sov siv. Feem ntau, martensitic stainless hlau muaj qhov hardness ntawm 400-600 hv, siab dua li ntawm austenitic thiab ferritic stainless hlau. Qhov siab hardness no ua rau nws zoo tagnrho rau kev siv nrog kev hnav tseem ceeb thiab ua haujlwm ntev, xws li cov cuab yeej tsim khoom thiab cutlery.
Tensile zog
