All our pins are made out of quality 4340 bar stock. After machining pins are Quenched and Double Tempered to increase core strength. This is followed by deep case induction hardening. Final product has high bending strength and excellent wear resistant properties.
Our Track Bushes are made out of Q&T 4140 material and induction hardened on the inside diameter only. This process enables us to put deeper case on to the bush in the wear area only. Rest of the bush material remains at lower hardness that can absorb shocks sustained in the service.
