Product Description

Leading Manufacturers, Suppliers of C45 Round Bars, 1045 Steel Bars , S45C Steel Bars – EN 1.0503, UNS G10450

SAE-AISI 1045 is an alloy of iron, further classified as a carbon steel. 1045 is the SAE-AISI designation for this -material. 1.0503 is the EN numeric designation. And G10450 is the UNS number. AISI 1045 is a medium carbon steel is used when greater strength and hardness is desired.

Weldability: Due to the medium-high carbon content it can be welded with some precautions.

Hardenability: It has a low hardenability in water or oil; fit for surface hardening that gives this steel grade a high hardness of the hardened shell.

Machinability: C45 Steels have good machinability in normalized as well as the hot rolled condition.
