An ultra high carbon steel with a fine grained iron matrix stabilized by cementite in predominantly spheroidized form at elevated temperatures. A method for treating the steel including heat treatment and mechanical working under sufficient deformation to refine the iron grain and spheroidize the cementite. Mechanical working is preferably performed either in the upper alpha-cementite range or in the gamma-cementite range. Thermal cycling may be substituted for mechanical working. An alternative method is mixing and sintering fine cementite containing-iron alloy powders and iron powders.
