Steel
Steel 1045
Applications
Used in gears, shafts, axles, bolts, studs, and machine parts.
Forgeability
Can be hammer forged and responds to heat treatment.
Heat Treatability
Suitable for flame and induction hardening.
Principle Design Features
1045 is a medium carbon steel is used when greater strength and hardness is desired than in the "as rolled" condition. Extreme size accuracy, straightness and concentricity combine to minimize wear in high speed applications. Turned, ground and polished bars can be machined unsymmetrically with minimum distortion.
