Cov ntaub ntawv xav tau
Cov khoom ntawm lub nres disc txais kuv lub teb chaws grey cam khwb cia hlau 250 tus qauv, hu ua HT250, uas yog sib npaug rau American G3000 tus qauv. Cov kev cai rau peb lub ntsiab tseem ceeb ntawm cov tshuaj muaj pes tsawg leeg yog: C: 3.1∽3.4 Si: 1.9∽2.3 Mn: 0.6∽0.9. Mechanical kev ua tau zoo: tensile zog> = 206MPa, dabtsi yog khoov zog> = 1000MPa, deflection> = 5.1 hli, hardness yuav tsum nruab nrab ntawm: 187∽241HBS.
