SAE1045 Round Bar S45C High Strength Quenching and Tempering Wear Resistant Carbon Steel Rod
AISI 1045 steel round bar is a high carbon steel under American standards, classified as a quenching and tempering steel with excellent strength properties. Available in hot rolled round bars, square bars, cold-drawing bars, and forged bars, this material is ideal for demanding industrial applications.
AISI 1045 round bar is widely used for manufacturing moving parts requiring high strength, including:
- Plunger of air compressor and pump
- Rolled shaft and connecting rod
- Endless screw and gear rack
- Dowel of heavy machines
- Crank axle and machine tool shaft
- Transmission shaft and wear resistant parts
