95MnWCr5 1.2825 Alloy Cold Work Tool Steel
Hom: Round bar
Lub sij hawm xa tuaj: Annealed dub nto / Tig ci nto / Q ntxiv T
Khoom Description
95MnWCr5 steel yog hom txias-ua haujlwm tuag hlau. Cov txheej txheem tau teev tseg tias cov hlau ua haujlwm txias 95MnWCr5 steel yog cov hlau alloy tuag nrog siab hardenability. Vim tias cov carbide tsim los ntawm tungsten hauv cov hlau, cov hlau no muaj ntau tshaj carbide thiab ntau dua hardness thiab hnav tsis kam tom qab quenching thiab kub tempering. Tsis tas li ntawd, tungsten kuj pab tswj cov nplej zoo thiab ua kom cov hlau tau zoo dua toughness. Yog li ntawd, cov cuab yeej ua los ntawm cov hlau ua haujlwm txias 95MnWCr5 hlau tsis tshua muaj ntug kev sib tsoo thiab tuaj yeem tswj tau qhov zoo thiab qhov loj ntawm cov hniav.

Kev ua tau zoo
Qhov ntev viscous chips qhia lub machinability ntawm lub alloy. Nws tuaj yeem ua tiav hauv lub xeev annealing, tab sis lub xeev H1150M yuav tsim cov txiaj ntsig zoo tshaj plaws. Yog tias cov khoom raug ua tiav hauv qhov no, cov khoom yuav tsum tau ua tiav tom qab kev daws teeb meem ua ntej qhov kawg hardening.
