Nta:
1) Universal HSS: W18Cr4V Tool Steel Bar feem ntau yog siv rau hauv kev tsim cov khoom siv hlau ntawm kev txiav hardness HB 300 lossis tsawg dua cov cuab yeej txiav (xws li laum, kais, saw hniav) thiab cov cuab yeej txiav (xws li hob, pinion cutter, broach), feem ntau siv muaj W18Cr4V steel qib, W6Mo5Cr4V2, thiab lwm yam

2) Lub hom phiaj tshwj xeeb HSS: W18Cr4V kev kub ceev cuab yeej Hlau, suav nrog cobalt kev kub ceev steel thiab superhard kev kub ceev steel (hardness HRC68-70), feem ntau yog siv rau hauv kev tsim cov hlau txiav (xws li kub kub alloy, titanium alloy.
siab zog steel, thiab lwm yam) thiab cov cuab yeej txiav, feem ntau siv qib steel muaj W12Cr4V5Co5, W2Mo9Cr4VCo8, thiab lwm yam.

3) Cov cuab yeej txiav ua los ntawm W18Cr4V kev kub ceev cov cuab yeej hlau, ntxiv rau vim nws qhov siab hardness, siab hnav tsis kam
thiab toughness txaus, muaj lwm yam tseem ceeb yog ib tug liab hardness.
