AISI 1045 Steel Round Bar Overview

AISI 1045 steel round bar is a high carbon steel under American standards, classified as a quenching and tempering steel with high strength characteristics. This alloy steel is available in various forms including 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

This material is commonly used in quenching and tempering and normalizing delivery states, and after high-frequency quenching or shot peening for wear-resistant applications.
