W18Cr4V yog tungsten high-speed steel, nrog siab hardness, liab hardness thiab kub hardness. Kev kho cua sov ntau yam nyuaj rau overheat quenching, txheej txheem kev kho cua sov tsis yooj yim oxidation thiab decarbonization, kev sib tsoo zoo dua. Lub hardness ntawm cov hlau yog khaws cia ntawm HRC 63-64 thiab HRC 62-63 ntawm 500 ° C thiab 600 ° C, raws li, thiab muaj kev ua tau zoo txiav rau ntau cov ntaub ntawv dav dav.
