Properties of steel C45 (1.0503) 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.

WebC45 is a medium carbon steel grade offering reasonable tensile strength. Supplied in the cold drawn or hot rolled condition, tensile properties can vary but are approximately between 500-800 N/mm². This grade can be flame or induction hardened to produce a good surface hardness with moderate wear resistance.
