1045 TGP Precision Steel Round

1045 TGP Precision Steel Round

Characteristics

C1045 Precision Round, is a medium carbon steel round that has been ground and polished to a high degree of concentricity, surface perfection, straightness, and overall accuracy. Use C1045 Precision Round when a higher degree of added strength, dimensional accuracy and straightness are required. Typical Diameter Tolerance = plus 0" / minus .001".

1045 Turned, Ground and Polished Precision Shafting - C1045 TG&P is a silicon killed medium carbon steel. Higher carbon content imparts increased strength over low carbon steels, such as 1018. Turned, Ground and Polished Shafting is produced by turning instead of cold drawing. Since the internal stresses set up in the cold drawing process is avoided, the possibility of warpage and distortion is minimized. Grinding and polishing provides a finished size of greater accuracy and surface smoothness. Turned, Ground and Polished Precision Shafting represents the highest degree of over-all accuracy, concentricity, straightness, and surface perfection attainable in commercial practice. Turned, Ground and polished Precision Shafting is normally produced undersize of nominal, which lends favorably to fit standard bearings. Response to heat treatment is excellent and the resultant mechanical properties which can be obtained permit wide usage in the production of machinery parts and shafts. 1045 can be hammer forged, machinability is good, but forming and welding qualities are limited.

This is medium-carbon steel. The higher content imparts higher strength properties than 1018 steel. When higher degrees of dimensional accuracy and straightness are required, use Precision shafting. Due to the higher carbon content this material is not readily welded.

Precision Shafting represents the highest degree of over-all accuracy, concentricity, straightness, and surface perfection attainable in commercial practice. After being ground on centerless grinders, bars are polished to a high finish and carefully straightened.

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.
