  AISI 1045 steel has good machinability in normalized as well as the hot rolled condition. Based on the recommendations given by the machine manufacturers, operations like tapping, milling, broaching, drilling, turning and sawing etc. can be carried out on AISI 1045 steel using suitable feeds, tool type and speeds.


AISI 1045 steel is readily welded when correct procedure is followed.

Welding AISI 1045 steel in through-hardened, tempered and flame or induction hardened condition is not recommended.

Low hydrogen electrodes are preferred for welding AISI 1045 steel.

The workpiece is

Pre-heated at 200°C–300°C (392°F - 572°F)

Maintained at the same temperature during welding

Cooled slowly using sand, ashes etc and

Stress relieved at 550°C - 660°C (1022°F - 1220°F).
