ABSTRACT:
A method for manufacturing a connecting rod for an engine contemplates creating a rough connecting rod from high carbon steel. The rough connecting rod is normalized to provide strength and toughness characteristics to the core of the connecting rod for functional operation. A first, second or both ends of the connecting rod are selectively induction hardened to create a durable martensitic structure in those ends. The connecting rod is then cracked and ground to form a final connecting rod for use in internal combustion engines.
