Product Description
ASTM SAE 1045 Medium Tensile Hot Rolled Steel Bar
Carbon Steel Round Bar / Rod 12 - 320mm
Product Overview
AISI 1045 steel round bar is a high carbon steel under American standard, classified as a quenching and tempering steel with high strength properties. This versatile alloy steel can be produced as hot rolled round bars, square bars, cold-drawing bars, and forged bars.
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
