Cov cuab yeej steel" txhais tau tias cov pa roj carbon thiab alloy steels haum rau siv hauv kev tsim cov cuab yeej, cov hlau no muaj cov yam ntxwv siab hardness, tsis kam hnav, toughness thiab tsis kam mus softening ntawm qhov kub thiab txias. reamers, xyaum, tshuab cuab yeej pwm thiab tes cuab yeej.
Lawv muab faib ua ntau pawg raws li lawv cov yam ntxwv thiab muaj pes tsawg leeg. Cov cuab yeej steel tau muab faib ua xya yam tseem ceeb: dej-hardened steels, kub-ua haujlwm steels, txias-ua hauj lwm steels, cuam tshuam-resistant steels, tuag steels, high-ceev steels thiab tshwj xeeb-lub hom phiaj cuab yeej steels. Piv txwv li, lub xub ntiag ntawm carbide-forming ntsiab xws li chromium, vanadium, molybdenum thiab tungsten yog lub ntsiab qhia cov yam ntxwv ntawm high-ceev cuab yeej steels. Lawv qhov kev ua tau zoo ntawm qhov kub siab yog txhim kho los ntawm kev sib ntxiv ntawm cobalt lossis npib tsib xee. Cov cuab yeej steel feem ntau raug kho kom sov kom ua kom tawv thiab siv rau hlau stamping, sib sau, shearing, txiav thiab yas molding.
