1045 Turned, Ground and Polished Precision Shafting is a silicon killed medium carbon steel. Higher carbon content gives it increased strength over low carbon steels, such as 1018. Turned, Ground and Polished Shafting is produced by turning instead of cold drawing the stock down to its nominal size. 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. Response to heat treatment is excellent and the mechanical properties permit a 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.
