AISI 1045, a medium tensile carbon steel, is widely used for
industrial applications requiring more wear-resistance and
strength. From bolts and studs to gears and axles, 1045 is
characterized by good weldability and machinability as well as high
strength and impact properties in either the normalized or
hot-rolled condition.
Typical applications for this grade include:
- Bolts
- Fasteners
- Shafts
- Yokes
- Hubs
- Gears
- Axles
- Casters
