Kev kub ceev hlau yog ib hom hlau nyuaj, thiab nws cov ntsiab lus carbon feem ntau yog nyob nruab nrab ntawm 0.70 thiab 1.65 feem pua. Cov ntsiab lus ntawm cov ntsiab lus alloy yog siab, thiab tag nrho cov nyiaj tuaj yeem ncav cuag 10-25 feem pua.
Kev kub ceev steel tuaj yeem muab faib ua cov hom phiaj dav dav hlau thiab lub hom phiaj tshwj xeeb steel raws li lub hom phiaj sib txawv.
① Universal high-speed steel: feem ntau yog siv los tsim cov cuab yeej txiav (xws li laum, kais, saw hniav) thiab cov cuab yeej precision (xws li hob, iav shaper, broach) rau txiav cov khoom hlau nrog hardness HB tsawg dua lossis sib npaug li 300. Cov qib steel muaj xws li W18Cr4V, W6Mo5Cr4V2, thiab lwm yam.
② Kev kub ceev steel rau lub hom phiaj tshwj xeeb: suav nrog cobalt kev kub ceev steel thiab superhard high-speed steel (hardness HRC68 ~ 70), feem ntau yog siv los ua cov cuab yeej txiav nyuaj rau tshuab hlau (xws li superalloys, titanium alloys thiab high-strength steel). Cov qib steel feem ntau yog W12Cr4V5Co5, W2Mo9Cr4VCo8, thiab lwm yam.
Kev siv lub ntsiab ntawm cov hlau dav dav yog nws qhov muaj zog ntau yam, uas yog dav siv los tsim cov tho, reamers, kais, milling cutters, iav cutters thiab broaches.
Kev ua haujlwm siab steel feem ntau yog siv los ua cov cuab yeej kub sib sau thiab cov cuab yeej uas cuam tshuam thiab muaj cov qauv tsis muaj zog.
