Description

1045 cold rolled round bars are an excellent candidate for most processing techniques. 1045 cold rolled steel round bars have a smooth dark grey oiled surface with accurate dimensions throughout. 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. Commonly used in gears, shafts, axles, bolts, studs and machine parts.
