The track link has been done special hardening treatment which ensures its high strength and abrasion resistance.

Inductive harden surface

The bushing shaft has been carburized and quenched the surface with medium frequency, which guarantees its reasonable hardness of core and abrasion resistance of the inner and outer surfaces.

The pin shaft is quenched the surface with medium frequency after quenching and tempering, which ensures it’s sufficient core strength and wear-resistance of inner and outer surfaces.
