1, Cov khoom sib txawv
1. Cov cuab yeej ntawm chrome vanadium hlau: ib qho cuab yeej alloy steel nrog chrome vanadium alloy caij.
2. Cov cuab yeej carbon steel: hlau carbon alloy nrog cov ntsiab lus carbon ntawm 0.0218 feem pua ~ 2.11 feem pua
2, Cov yam ntxwv sib txawv
1. Cov yam ntxwv ntawm chrome vanadium steel: tom qab kev kho cua sov, lub hardness yog siab dua 60HRC (Rockwell hardness), thiab nws muaj kev hnav zoo nyob rau hauv tej yam kev ua haujlwm.
2. Carbon steel nta: tus nqi qis, cov txheej txheem zoo heev (xws li weldability thiab txias formability). Feem ntau, qhov siab dua cov ntsiab lus ntawm cov pa roj carbon steel, qhov hardness thiab lub zog ntau dua, tab sis cov yas qis dua.
