1045 Cold Rolled Steel Plate
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.

PRODUCT DETAILS
Carbon steels are a category of steels with 0.12 to 2% carbon content. AISI 1045 is a medium carbon steel designed to be able to function in areas requiring greater strength and hardness. This steel possesses excellent size accuracy, concentricity, and straightness which together enable to minimize wear in high speed applications. AISI 1045 can be formed into turned, ground and polished bars that can be machined unsymmetrically with limited distortion.
