The characteristics of rolled steel rod Hot rolled mild steel in the shape of a round bar with the designation 1045. Forging, heat treatment, cold drawing, machining, and other processes are all suitable for medium carbon steel. The strength of 1045 after heat treatment is higher than that of lower carbon steels. Although grade C1045 may be hammer forged and has acceptable machinability, it has limited shaping and welding capabilities. discount Cold Drawn Round Bar website:http://www.cncoraltech.com/drawn-bar/cold-drawn-round-bar/
