C60 steel is an unalloyed medium carbon engineering steel which has 0.57%-0.65% Carbon as per EN10083 standard.It has characteristics similar to that of C55 carbon steel which has high hardness and high strength after hardening.C60 is difficult to weld,and machinability is poor due to high carbon content.This steel is generally supplied in an untreated or normalised condition.
