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
