42Crmo Hloov Hlau (GB / T 3077) yog chromium- molybdenum} molybdenum envoyered rau siab zog, nrog cov khoom siv neeg kho tshuab:
Lub zog tensile: 1080-1300 MPA tom qab quenching (850 degree) thiab kev kawm tiav (550 degring)
Tos lub zog: ntau dua los yog sib npaug rau 930 MPa, kom ntseeg tau tsawg heev nyob rau hauv lub torque-{1}} tseem ceeb rau cov khoom siv hnyav rau cov khoom siv hnyav.
Kev Cuam Tshuam Cov Khoom Siv: Loj dua lossis sib npaug nrog 63 J ntawm 20℃(Retigy v {} NECH} NEX NECHNE Torque spikes (piv txwv li, hauv kev lag luam gearboxes).
Hardness: 298-341 HB Tom qab kev kho cua sov, ntsuas cov ris kev tiv taus thiab lub tshuab luam ntawv rau precision {{} cov khoom siv.
