Cov yam ntxwv ua tau zoo ntawm cov cuab yeej high-speed steel nrog lub hom phiaj
(1) siv cov hlau DianZhaLu smelting, cov ntsiab lus silicon tsis tau teev tseg.
(2) txhawm rau txhim kho steel txiav machining, tus neeg yuav khoom thov, tuaj yeem yog cov kev cai rau sulfur ω (S) 0.60 feem pua ~ 0.15 feem pua.
(3) ntawm cov khoom seem hauv cov hlau (qhov loj me): 0.30 feem pua lossis Ni; Cu 0.25 feem pua lossis tsawg dua.
(4) yog cov ntsiab lus siab tungsten molybdenum tso cai ω (Mo) ntau dua 1.00 feem pua . Cov hlau tungsten molybdenum thiab kev sib raug zoo yog: thaum molybdenum cov ntsiab lus ntau dua ω (Mo) 0.30 feem pua, tungsten cov ntsiab lus txo qis sib xws, hauv molybdenum cov ntsiab lus ntau dua ω (Mo) 0.30 feem pua , txhua ω (Mo) 1 feem pua tau hloov ω (W) 2 feem pua, yog tias ua tau raws li qhov xwm txheej no, hauv GangHao no ntxiv tom qab "Mo".
(5) W6Mo5Cr4V2 steel raws li ob qho tib si cov khoom thiab cov lus pom zoo, kho cov ntsiab lus ntawm vanadium ω (V) 1.60 feem pua ~ 2.20 feem pua.
