ASTM SAE8620 20CrNiMo Alloy Seamless Steel Yeeb Nkab

ASTM SAE8620 20CrNiMo Alloy Seamless Steel Pipe Featured duab

Lus piav qhia luv luv:

20CrNiMo yog cov khoom siv hlau zoo zoo nrog cov khoom siv zoo heev, kev tiv thaiv corrosion thiab hnav tsis kam.Nws yog dav siv hauv tshuab, engineering, kev tsim kho thiab kev tiv thaiv ib puag ncig.Nws lub zog siab, zoo toughness thiab ductility pab kom nws muaj kev pab lub neej ntev nyob rau hauv hnyav ib puag ncig thiab tiv taus siab loads, muab kev txhawb zog rau kev loj hlob ntawm niaj hnub kev lag luam thiab engineering.

20CrNiMo Alloy Seamless Steel Yeeb Nkab

20CrNiMo yog thawj tus lej 8620 hauv Asmeskas cov qauv AISI thiab SAE.Lub hardenability kev ua tau zoo zoo ib yam li cov hlau 20CrNi.Txawm hais tias Ni cov ntsiab lus nyob rau hauv cov hlau yog ib nrab ntawm 20CrNi hlau, vim yog qhov sib ntxiv ntawm cov khoom me me ntawm Mo, lub sab sauv ntawm austenite isothermal transformation nkhaus txav mus rau sab xis;thiab vim qhov tsim nyog nce hauv Mn cov ntsiab lus, qhov hardenability ntawm cov hlau no tseem zoo heev, thiab lub zog Nws kuj yog siab dua 20CrNi steel, thiab tseem tuaj yeem hloov 12CrNi3 steel los tsim cov khoom carburized thiab cyanide qhov chaw uas yuav tsum tau ua haujlwm siab dua.20CrNiMo tuaj yeem tiv taus qhov kub thiab txias ntxiv rau cov khoom zoo vim nws muaj molybdenum.

Daim ntawv thov teb

1. Hauv kev lag luam tsim khoom, feem ntau yog siv los tsim cov khoom lag luam uas yuav tsum muaj kev thauj khoom siab, kev ntxhov siab, thiab hnav siab, xws li lub zog, ncej, bearings, thiab lwm yam. Lawv lub zog siab thiab zoo toughness ua rau cov khoom no kom muaj kev ruaj ntseg. ntev kev pab cuam lub neej nyob rau hauv hnyav ua hauj lwm ib puag ncig.Tsis tas li ntawd, nws kuj muaj kev qaug zog zoo heev thiab kev tiv thaiv corrosion, uas tuaj yeem tiv taus qhov yaig ntawm qhov chaw sab nraud thiab xyuas kom ruaj khov ntawm cov khoom siv.

2. Hauv kev tsim kho, cov hlau no tau siv dav hauv kev tsim cov qauv loj xws li txuas hniav thiab cov tsev siab siab vim nws lub zog siab thiab zoo ductility.Nyob rau hauv cov qauv no, lawv tuaj yeem tiv taus lub siab loj thiab nruj, ua kom muaj kev nyab xeeb thiab ruaj khov ntawm lub tsev.

3. Tsis tas li ntawd, nrog rau kev txhim kho ntawm ib puag ncig kev paub, kev siv hauv kev tiv thaiv ib puag ncig tau dhau los ua ntau dua.Piv txwv li, nyob rau hauv lub zog tshiab tsheb, nws tuaj yeem siv los tsim cov khoom tseem ceeb xws li lub cev muaj zog thiab cov reducers, pab txhawb kev mus ncig ntsuab.Nws tseem ua lub luag haujlwm tseem ceeb hauv cov cuab yeej tiv thaiv ib puag ncig xws li kev kho dej phwj thiab kev kho cov roj khib nyiab, muab kev txhawb zog rau kev txhim kho ib puag ncig zoo.

Daim ntawv thov teb

1. Cov khoom siv tseem ceeb, xws li cov khoom siv dav hlau tsaws, cov tso tsheb hlau luam thiab cov khoom siv tsheb armored.

2. High-strength fasteners thiab connectors.

3. High load gears thiab bearings.

Kev kho cua sov Specification

Kev 850ºC, roj txias;Kub 200ºC, cua txias.

Delivery Status

Kev xa tawm hauv kev kho cua sov (normalizing, annealing lossis kub tempering) lossis tsis muaj kev kho cua sov, qhov xwm txheej ntawm kev xa khoom yuav tsum tau qhia hauv daim ntawv cog lus.
