1045
A medium carbon steel used for heat treating
(Quenching & Tempering)
1045 has a fair response to conventional quenching and it is widely used where requirements are not too stringent. It is also used extensively in induction hardening applications.
This is not normally considered a screw machine steel and is only fair for brazing and welding. However, it can be forged satisfactorily and is the most common shafting steel in the medium carbon range.
