Carbon Steel


AISI 1045 Steel

AISI 1045 Steel is medium tensile steel supplied in the black hot rolled or normalized condition. It exhibits good weldability, good machinability, and high strength and impact properties to be used in various industrial applications.

AISI 1045 steel has a low through-hardening capability that recommended for tempering and through-hardening.  Carbon steel AISI 1045 is a medium carbon, medium tensile steel supplied as forged or normalized. This steel shows reasonable strength and toughness. 1045 is the designation in both the SAE and AISI systems for this material. G10450 is the UNS number.

SAE 1045 Steel is used extensively by all industry sectors for applications requiring more strength and wear resistance than low carbon mild steels.
