1045 TG&P Carbon Steel Bar

At Industrial Tube & Steel, our carbon steel products are high-quality and durable to meet your specific needs. 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, and good mechanical properties. 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 are avoided, the possibility of warpage and distortion is minimized. Grinding and polishing provide a finished size of greater accuracy and surface smoothness. Response to heat treatment is excellent and the mechanical properties permit wide usage in the production of machinery parts and shafts. 1045 can be hammer forged, and machinability is good, but forming and welding qualities are limited.
