Product Description
SAE 1045 / S45C / S45K Cold Drawn Bar
Carbon steel round bars available in diameters from 2-100 mm, manufactured through cold drawing process for enhanced dimensional accuracy and surface finish.
Product Overview
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 and square bars, cold-drawn bars, and forged bars, this material is suitable for various industrial applications requiring high strength and durability.
Applications
- Moving parts requiring high strength: air compressor plungers, pump components
- Rolled shafts, connecting rods, endless screws, gear racks
- Dowels for heavy machinery
- Wear-resistant parts after high-frequency quenching: crank axles, machine tool shafts, transmission shafts
Material Properties
1045 is a commonly used low carbon steel alloy offering good strength, ductility, and excellent machinability. Typically supplied in quenching and tempering or normalizing delivery states.
