Abstract:
A method of producing a carburizing forging material includes heating a steel material at 1300° C. or higher, forming Nb in a solid solution state and then rolling the steel material, heating the rolled steel material in a range of 950 to 1050° C., hot forging the heated steel material in a range of 950 to 1040° C., precipitating a Nb carbonitride in the steel material by cooling the steel material or maintaining a temperature of the steel material under a condition in which a time spent in a range of 950 to 970° C. is 1 minute or longer, precipitating a ferrite phase in the steel material by cooling the steel material or maintaining a temperature of the steel material under a condition in which a time spent in a range of 730 to 870° C. is 10 minutes or longer, and cooling the steel material to room temperature.

Claim (Index 4):
The method according to  claim 1 , wherein a content ratio of P included in the steel material is 0.03 mass % or less.
