AISI/SAE 1045 C45 Carbon Steel Bar Description

1045 is characterized by medium carbon, medium tensile strength steel, which has quite good strength, machinability and reasonable weldability under hot-rolled conditions. 1045 round steel can be provided with hot rolling, cold drawing, rough turning or turning and polishing. By cold-drawing the 1045 steel bar, the mechanical properties can be improved, the dimensional tolerance can be improved, and the surface quality can be improved.
