1045 is a medium carbon steel. Higher carbon content imparts increased strength over low carbon steels.  Response to heat treatment is excellent and the resultant mechanical properties which can be obtained permit wide usage in the production of machinery parts and shafts. 1045 can be hammer forged, machinability is good, but forming and welding qualities are somewhat limited.
