Tus kav dejnto hardness ntawm Astm ASTM 269 Hardness Max. RB 90 siv 100kg 1/16 "lub pob uas hla uas tsoo lub raj thiab siv qhov nruab nrab ntawm tawv ntawm sab nraud ntawm cov tub ntxhais lub cheeb. Vickers micro hardness siv siv 50 Grammis Diamond CONE uas qhia txog lub raj thiab muab ib qho nyuaj rau kev ntsuas ntawm ib qho chaw ntawm sab nraud ntawm lub khob hliav qab.
