AISI 10450 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.
Carbon steels are a category of steels with 0.12 to 2% carbon content. AISI 1045 can be formed into turned, ground and polished bars that can be machined unsymmetrically with limited distortion
