Hnav steel phaj: kev daws qhov kawg rau kev ua txhaum tsis kam
Hardness yog cov khoom tseem ceeb ntawm cov ris-tiv taus steel daim hlau, raws li peb cov tsiaj ua haujlwm yog qhov tseem ceeb tshaj plaws rau kev xaiv cov khoom lag luam zoo nkauj Daim Ntawv Thov .} Seb siv Brinell, Rockwell, lossis kev xeem kom paub tseeb lub neej ntev thiab kev txuag nqi.
