420 Stainless Hlau Yeeb Nkab

420 stainless hlau yeeb nkab steel yog lub siab- carbon martensitic stainless hlau), thiab ib qho me me), tsib), phosphorus (p), sulfur (s) thiab lwm yam ntsiab lus. Ntawm lawv, cov ntsiab lus chromium feem ntau yog ib feem ntau ntawm 12% -14%, thiab cov pa roj carbon nyob nruab nrab ntawm 0.26% -0.35%. Qhov kev faib ua feem ntawm cov khoom no muab 420 stainless yeeb nkab tshwj xeeb lub cev thiab tshuaj siv tshuaj. Nws yog dav siv nyob rau hauv ntau daim teb xws li kev tsim kho, kev tsim kho tshuab, kev lag luam tshuaj, kev kho mob roj av, thiab khoom noj, thiab tau dhau los ua cov khoom tseem ceeb hauv cov lag luam no.

Hnav zoo heev thiab siab tawv

Ua tsaug rau nws cov ntsiab lus carbon ntau thiab cov roj chromium, tom qab kev kho cua sov, lub zog ntawm 420 stainless hlau tuaj yeem ncav ntau dua 30% siab dua li ntawm 304 stainless hlau. Nyob rau hauv cov coj kev ntsuas tiv thaiv, cov hnav tiv thaiv kev ntsuas ntawm 420 stainless hlau yeeb nkab hlau yog li 25% siab tshaj li ntawm 304 stainless hlau.

Siab Zog

Cov yeeb nkab muaj roj carbon ntau ntawm 420 stainless hlau yeeb nkab ua kom cov hlau kom tau txais lub zog siab dua tom qab kev kho kom sov (xws li quenching thiab tempering). Tom qab kev kho cua sov, lub zog tensile ntawm 420 stainless hlau yeeb nkab tuaj yeem ncav cuag 735 MPa thiab cov txiaj ntsig lub zog tuaj yeem ncav cuag 540 MPA.

Zoo corrosion tsis kam

420 cov yeeb nkab stainless hlau muaj qhov sib npaug ntawm cov chromium, uas tuaj yeem tsim cov yeeb yaj kiab oxygen rau ntawm cov pa, dej vapor, thiab lwm yam kev sib kho hauv cov huab cua. Cov yeeb nkab txhua xyoo ntawm 420 stainless hlau yeeb nkab hauv 5% mm / xyoo, thaum lub xyoo corrosion ntawm cov hlau ua txhua xyoo yuav yog ntau li ntau millimeters / xyoo.

1. Qhov loj customization:Raws li cov kev xav tau ntawm tus neeg yuav khoom, hlau kav ntawm txawv diameters, cov phab ntsa thicknesses, thiab ntev tuaj yeem kho tau. Piv txwv li, txoj kab uas hla los ntawm ob peb millimeters rau ntau pua millimeters, lub phab ntsa tuab tuaj yeem raug txiav raws li cov kev xav tau tiag tiag.

2. Kho Kev Customization:Ntxiv nrog rau cov leeg ncig ua ke, square, duab plaub, thiab lwm yam tshwj xeeb {} Daim duab zoo li kuj tseem tuaj yeem ua kom tau raws li cov qauv tsim.

3. Nto Kev Kho Mob Kho Siab:Muaj ntau txoj kev kho ntawm cov kev kho mob ntau yam xws li piuldblasting, pickling, thiab muaj kev sib ntsib ntawm cov neeg yuav khoom rau cov tsos rau cov kav hlau.

4. Kev Ua Haujlwm Customization:Los ntawm kev kho cov txheej txheem kev kho cua sov, 420 stainless hlau yeeb nkab muaj peev xwm ua kom pom ntau cov tawv tawv, lub zog, yog li kev siv ntau yam xwm txheej.

Kev ua tshuab ntawm 420 stainless hlau yeeb nkab hlau yog qhov tseem ceeb rau nws cov khoom tau zoo thiab ua tau zoo. Cov hauv qab no yog cov kev ua tshuab ua ke thiab lawv cov ncauj lus qhia ntxaws ntxaws:

1. Kev kho cua sov:suav nrog quenching thiab tempering. Quenching tuaj yeem txhim kho lub hardness thiab hnav tsis kam ntawm cov kav hlau hlau; Tempering tuaj yeem tshem tawm quenching kev ntxhov siab thiab txhim kho cov tawv thiab cov yas ntawm cov kav hlau. Los ntawm kev tswj hwm cov khoom siv cua sov, cov khoom siv zoo tshaj plaws thiab microstructures ua tau.

2. Txias ua:Xws li cov ncu txias, txias kos duab, dabtsi yog khoov, thiab lwm yam txheej txheem. Cov txheej txheem no tuaj yeem txhim kho cov qauv raug thiab zoo ntawm cov kav hlau ua haujlwm thaum txhim kho lawv cov khoom siv me me thiab corrosion tsis kam.

3. Vuam:420 Stainless hlau yeeb nkab tuaj yeem sib txuas siv ntau txoj kev vuam, xws li Tig vuam, thiab vuam vuam.

4. Txiav thiab xuas nrig ntaus:Raws li cov kev xav tau ntawm tus neeg yuav khoom, 420 stainless hlau yeeb nkab tuaj yeem txiav thiab punched. Kev txiav cov txheej txheem suav nrog Laser Txiav, Ntshav Txiav, thiab lwm yam; Punching tuaj yeem ua tau los ntawm kev ua haujlwm, xuas nrig ntaus, thiab lwm yam.

Lub microstructure ntawm 420 stainless hlau yog feem ntau martensitic, tus cwj pwm los ntawm lub cev - centered tetragonal crystal crystal crystal crystal. Cov qauv qauv qauv no raws li qhov tshwm sim ntawm alloy cov pa roj carbon ntau thiab tuaj yeem ua kom tau yooj yim los ntawm kev kho cov txheej txheem cua sov.
