Cov cuab yeej ua haujlwm txias yog siv rau kev ua haujlwm txias ntawm cov hlau uas qis dua nws qhov kub thiab txias, lawv muaj qee qhov zoo hardness thiab hnav tsis kam ntawm qhov kub thiab txias tab sis qee zaum cov hlau tuaj yeem siv rau qhov kub siab, yog li ntawm qhov kub thiab txias, peb tuaj yeem pom tias lawv muaj kuj tsawg hardness. Nyob ntawm qhov nruab nrab siv rau lub hom phiaj quenching, txias ua hauj lwm cuab yeej steels tau categorized ua plaub hom raws li hauv qab no.
- Dej hardening cuab yeej steel: yuav tsum tau dej quenched, tsis zoo hardenability, zoo cuam tshuam & poob siab kuj, hnav-tiv taus thiab tsis tshua muaj nqi, siv rau blanking dies, threading dies, rauj, chisel, hniav, carpentry cuab yeej, riam, thiab lwm yam., zoo w1.
- Roj hardening cuab yeej steel: kuj zoo hardenability, tsawg distortion, thiab tsawg shrinkage thaum tshav kub kub kho, siv rau kev tuag, txiav cov cuab yeej, gauges, thiab lwm yam., xws li O2.
- Cua hardening cuab yeej steel: siab hardenability, tsawg distortion, zoo hnav tsis kam thiab qhov tob ntawm hardening, siv rau xov dov, intricate tuag duab thiab xuas nrig ntaus, xws li A2.
- HCHC (cov pa roj carbon siab chromium) cov cuab yeej steel: siab hardenability, zoo hardness thiab hnav tsis kam, siv los ua cov tuag, xov dov tuag, ntsuas, thiab cov cuab yeej txiav, xws li D2. Cov cuab yeej no yog cov roj quenched lossis cua quenched.
