Technical Overview
AISI 1045 is a medium carbon steel offering superior strength and hardness characteristics. This material provides excellent dimensional accuracy, concentricity, and straightness, making it ideal for high-speed applications where minimal wear is critical. The steel can be processed into turned, ground, and polished bars that maintain structural integrity during asymmetric machining operations.
