Typical Applications 1045 Turned, Ground and Polished Precision Shafting is used over 1045 cold roll or hot roll when higher dimensional accuracy and straightness in the production of shafts are required. This high degree of straightness is so important in high-speed shafting applications, as it serves to prevent vibration and wear on packings and bearings. 1045 TG&P is used crankshafts, high-speed motor shafts, axle shafts, pup shafts, etc. 1045 can be used where greater strength is required than can be obtained from the lower carbon steels. It responds to heat treatment, and a wide range of properties can be obtained. Grade: 1045 Finish: Turned Grnd & Polished
