AISI\/SAE 1045 C45 Round Steel Bar Description<\/strong><\/b><\/h2>\n

AISI 1045 steel is characterized by good weldability, good machinability and high strength and impact properties in the normalized or hot-rolled condition.\u00a0So\u00a0AISI 1045\u00a0steel bar\u00a0is 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\u00a0bars\u00a0that can be machined unsymmetrically with limited distortion.\u00a0They are often\u00a0used in\u00a0the production of\u00a0gears, shafts, axles, bolts, studs and machine parts.<\/p>\n
