AISI/SAE 1045 C45 Round Steel Bar Description
AISI 1045 steel is characterized by good weldability, good machinability and high strength and impact properties in the normalized or hot-rolled condition. So AISI 1045 steel bar 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 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. They are often used in the production of gears, shafts, axles, bolts, studs and machine parts.
