25CrMo4 alloy hlau yog aqis alloy structural steelcov ntaub ntawv, teej tug mus rau Cr-Mo series alloy structural steel. Los ntawmKev kho cua sovtxheej txheem, cov qauv thiab kev ua tau zoo ntawm cov khoom no tuaj yeem tswj tau zoo, nrog lub zog siab thiab hardness, nrog rau kev hnav zoo thiab corrosion kuj. Nws cov khoom siv zoo tshaj plaws thiab kev ua haujlwm kub ua rau nws siv dav hauv ntau yam engineering, tshwj xeeb tshaj yog nyob rau hauv lub sijhawm xav tau lub zog siab thiab kub ua haujlwm.Kev nqis peev castingyog ib qho ntawm cov txheej txheem rau kev tsim xws li precision qhov chaw.
Khoom nta
1.Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm 25CrMo4 alloy steel feem ntau suav nrog chromium thiab molybdenum, uas ua lub luag haujlwm tseem ceeb hauv kev txhim kho lub zog thiab tawv ntawm cov khoom. Qhov sib ntxiv ntawm chromium txhim khu kev tiv thaiv corrosion thiab hardness ntawm cov khoom, thaum molybdenum txhim kho qhov kub thiab txias zog thiab qaug zog. Tsis tas li ntawd, cov ntsiab lus ntawm carbon thiab manganese kuj raug tsim los ua kom zoo dua weldability thiab machinability, yog li cov khoom ua tau zoo nyob rau hauv kev ua haujlwm huab cua.
2. Mechanical Properties
Cov khoom muaj lub zog tensile zoo heev thiab lub zog tawm los, tuaj yeem tiv taus cov khoom hnyav thiab cuam tshuam, thiab ua kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov qauv nyob rau hauv siab load. Nws hnav tsis kam tso cai rau lub taub hau ruaj ruaj kom muaj kev pabcuam zoo hauv ib puag ncig nrog kev hnav tsis tu ncua, txo qhov zaus ntawm kev saib xyuas thiab hloov, yog li txhim kho kev ua haujlwm tag nrho.
3. Kev kho cua sov ua haujlwm
Kev ua tau zoo ntawm 25CrMo4 alloy hlau tuaj yeem txhim kho tau zoo los ntawm cov txheej txheem kho cua sov xws li normalizing, quenching thiab tempering. Cov txheej txheem no tuaj yeem kho lub microstructure ntawm cov khoom kom nws tuaj yeem tswj tau cov yas zoo thiab tawv thaum txhim kho lub zog, hloov mus rau qhov sib txawv ntawm kev ua haujlwm thiab kev thov. Nyob ntawm qhov chaw siv tshwj xeeb, kev kho cua sov tsis tuaj yeem raug tswj xyuas kom meej tias txhua lub taub hau mount ua tau zoo hauv nws daim ntawv thov tshwj xeeb.

Daim ntawv thov ntawm Kho Cov Ncej
1. Cov cuab yeej siv tshuab:
Hauv cov cuab yeej siv tshuab, xws li lub taub hau ruaj khov tuaj yeem siv los txuas cov ncej tsav, levers lossis lwm yam uas yuav tsum tau ua kom ruaj khov. Nws tuaj yeem ua kom ntseeg tau tias cov khoom no nyob ruaj khov thaum khiav ntawm kev kub ceev lossis nyob rau hauv qhov hnyav.
2. Cov khoom siv hauv tsev:
Hauv lub tshuab nqus tsev ntxhua khaub ncaws, tshuab ntxhua khaub ncaws lossis lwm yam khoom siv hauv tsev, xws li lub taub hau ruaj khov tuaj yeem siv los ua cov khoom siv rau sab hauv, xws li txuas cov kav dej, lub cev muaj zog lossis lwm yam khoom tseem ceeb. Nws cov qauv ruaj khov thiab yooj yim-rau-kev sib txuas tsim ua rau kev saib xyuas thiab hloov cov khoom yooj yim dua.
3. Cov cuab yeej muaj:
Hauv kev cob qhia lossis cov chaw tsim khoom, cov taub hau ruaj khov no tuaj yeem siv los ua cov khoom siv hluav taws xob, cov cuab yeej tes lossis cov clamps. Lawv pab tswj kev ruaj ntseg ntawm cov cuab yeej thiab txhim kho kev ua haujlwm thiab kev nyab xeeb.
4.Auto qhov chaw:
Hauv kev lag luam tsheb tsim lossis kev saib xyuas, lub taub hau ruaj khov tuaj yeem siv los txuas lossis kho qhov chaw tsheb, xws li lub cav qhov chaw, lub tshuab ncua kev kawm lossis lub tshuab nres. Nws cov kav ntev thiab kev ntseeg siab yog qhov tseem ceeb los xyuas kom meej qhov kev ua tau zoo thiab kev nyab xeeb ntawm lub tsheb.
