The 1045 medium and high-strength carbon steel round rod/bar is characterized by a tensile strength ranging from 570 to 700 MPa, offering excellent weldability, machinability, and formability. It can be welded and processed into various shapes and sizes, making it widely applicable as raw material for industrial components such as shafts, gears, bolts, studs, automotive parts, and equipment used in industrial stations.

| 5.Welding | ||||
| 1045 is readily weldable in the as rolled and normalised condition providing the correct procedure is employed.Following welding the work piece immediately upon cooling to hand warm should be stress relieved at 550 oC - 660 oC if possible.
NB. Welding in the hardened and tempered, flame or induction hardened condition is not recommended. |
