Deep sensing hardened tread 

the track link has been done
the mediumfrequency hardening
treatment, which ensures its
highest strength and abrasion
resistance.

* Track links are forged,quenched and tempered.
* Rail deep hardened,with average surface hardness HRC53.
* Track bushings treated in a special furnace for high temperature carburizing.
* Deep hardened pins for best resistance to wear and fatigue.
* Track shoes heat treated for proper thoughness and wear resistance.

1.The track group with shoes is through quench-tempering processes to guarantee excellent mechanical properties, high strength and superior wear resistence to bending and breakage.

2.The surface hardness of the track group with shoes is HRC50-58 for reduced wear and longer life,
adding value to your products further to your business by maximizing durability of your products.
