Nco tseg:
1. Brinell Hardness: Nws yog tsuas yog siv los ntsuas qhov nyuaj ntawm cov cuab yeej, tsis quav ntsej hlau, kub-rolled biltse thiab annealed. Qhov ntsuas tau yog ≥HB450.
2. Rockwell Hardness: HRA feem ntau yog siv rau cov ntaub ntawv hardness loj dua li HRC67, xws li cov pa roj av siab dua li HRC67, thiab lwm yam ntsuas yog HREH> 70. HRC feem ntau yog siv los ntsuas qhov tawv ntawm cov hlau (xws li cov hlau steel, tuam hlau, alloy steel, thiab lwm yam) tom qab quenching lossis tempering. Qhov ntsuas tau yog HRC20 ~ 67.
3. Vickers Hardness: Siv los ntsuas qhov nyuaj ntawm cov khoom nyias nyias thiab tseem siv tau los ntsuas qhov nyuaj ntawm cov khoom tawv xws li carburizing, cyanking, thiab nitrival.
