M35 Kev kub ceev steel phaj
M35 cobalt high-speed steel, thaum piv rau cov nqi qis dua cov txheej txheem yooj yim dua, tuaj yeem ua tiav qhov tshwj xeeb hardness (HRC 67-70) thiab siab tawv tawv (HRC 63-65 ntawm 625 degree rau 4 teev) los ntawm kev kho cua sov kom tsim nyog. Nws kuj pom zoo hnav tsis kam thaum tuav lub zog thiab khoov lub zog piv rau cov qauv high-speed steels, zoo txo cov teeb meem xws li ntug vau thiab tawg hauv pwm.
Cov yam ntxwv tseem ceeb ntawm M35 high-speed steel yog nws cov ntsiab lus cobalt, uas txhim kho nws cov kev ua tau zoo raws li cov cuab yeej txiav universal tuag steel nrog quenching hardness xws li 1200 degree txog 1240 degree. Nws cov ntawv thov tseem ceeb suav nrog hobs, broaches, thiab kawg milling cutters.
Cov qauv sib piv suav nrog: AISI-M2 thiab JIS-SKH51.
Cov xwm txheej hauv tsev koom nrog spheroidizing annealing hauv qab 225 degree.
Nta thiab Daim Ntawv Thov: Qhov no tungsten-raws li high-speed steel yog zoo tagnrho rau kev tsim cov cuab yeej uas yuav tsum muaj ob qho tib si hnav tsis kam thiab cuam tshuam resilience rau kev ua haujlwm zoo. Nws yog qhov tsim nyog rau kev xuas nrig ntaus tuag, ntsia hlau tuag, cov cuab yeej tsim nyog rau qhov nyuaj hauv cov duab, reamers, milling cutters, hlau taub hau, xuas nrig ntaus thiab lwm yam.
Forging kub li ntawm 1100 degree mus rau 900 degree.
Annealing muaj cua sov cov khoom rau ntawm 800 degree thiab 850 degree; nws yuav tsum tau tuav ntawm qhov ntsuas kub no li ntawm 2-4 teev ua ntej txias hauv qhov cub.
Cov cua txias tuaj yeem suav nrog cua txias lossis roj quenching ua raws li kev ntsuas kub ntawm 550 degree thiab 580 degree.

Mos Annealing
Tshav kub rau 820-880oC, txias maj mam hauv qhov cub. Qhov no yuav tsim qhov siab tshaj plaws Brinell hardness ntawm 230-300.
Kev ntxhov siab
Kev ntxhov siab kom tshem tawm cov kev ntxhov siab yuav tsum tau ua los ntawm cua sov mus rau 650oC, tuav rau ib teev thaum tshav kub, ua raws li cua txias. Qhov kev ua haujlwm no yog ua los txo qis kev sib txawv thaum kho cua sov.
Hardening
Kub rau 450-600oC, preheat rau 850oC thiab tom qab ntawd mus rau 1050oC. Harden los ntawm qhov kub ntawm 1210-1250oC ua raws li cov roj, cua quenching los yog da dej sov 550oC. Hardness tom qab quenching yog 64-66 HRC.
Kev hloov pauv kub: Ac1=824oC, Ac3=853oC.
Tempering
Tempering kub: 3 x 1 teev ntawm 540-570oC.
