Track link:
The track link has been done the medium-frequency hardening treatment, which ensures its highest strength and abrasion resistance.
Track bushing:
The bush is done the carbonization and the surface medium-frequency quenching treatment, which ensures the reasonable hardness of core and abrasion resistance of internal and external surfaces.
Track pin:
The pin is done the termpering and the surface medium-frequency quenching treatment, which ensures the sufficient hardness of core and abrasion resistance of external surfaces.
