1.Tool steel yog ib hom hlau alloy tsim los siv rau ntau yam cuab yeej thiab machined Cheebtsam.Nws muaj pes tsawg leeg yog tsim los muab kev sib xyaw ntawm hardness, lub zog, thiab hnav tsis kam.Cov cuab yeej hlau feem ntau muaj cov pa roj carbon ntau (0.5% mus rau 1.5%) thiab lwm yam alloying xws li chromium, tungsten, molybdenum, vanadium, thiab manganese.Nyob ntawm daim ntawv thov, cov cuab yeej hlau kuj tseem muaj ntau yam khoom, xws li npib tsib xee, cobalt, thiab silicon.
2.Qhov tshwj xeeb ua ke ntawm cov khoom siv alloying siv los tsim cov cuab yeej steel yuav txawv nyob ntawm qhov xav tau thiab daim ntawv thov.Cov cuab yeej siv feem ntau yog muab faib ua cov hlau kub ceev, cov hlau ua haujlwm txias, thiab cov hlau ua haujlwm kub. "
