1045 CF - Medium Carbon Steel Bar

1045 CF is a medium carbon steel used extensively in induction hardening applications. It can be forged satisfactorily and is the most common shafting steel in the medium carbon range.  Due to its carbon content, 1045 CF bar is only fair for welding or brazing. It is also not typically considered a screw machine steel.

The CF stands for cold finished, which provides increased machinability and mechanical properties. Cold finished bars are produced from Special Bar Quality Hot Rolled Bars which are put through cold drawing, turning, grinding, or a combination of these methods. The cross-sectional area of the hot-rolled bar is then cold reduced for accurate size and smooth surface. Read our PDF on cold finished steel bar for more information.
