CAT 3406E crankshaft(6I1453) is made from high-quality raw materials 40Cr. Compared to cast iron crankshafts, they offer 27.9% higher tensile strength and 78.6% higher yield strength. The unique induction hardening process creates a 3-5 mm hardened layer (HRC 52-58), which improves wear resistance by 15% compared to nitrided cast iron. Our crankshafts have earned the trust of distributors worldwide.
