摘要： PROBLEM TO BE SOLVED: To provide an advantageous method for manufacturing a cold-worked article, which can effectively inhibit crystal grains from being coarsened even when strain due to heat treatment is formed, while securing the strength and toughness of the inner part of the article even when the article has been subjected to such carburization treatment as to cause the strain due to heat treatment. SOLUTION: A base steel material of the article has a composition including, by mass%, 0.1 to 0.4% C, 0.01 to 1.2% Si, 0.01 to 2.0% Mn, 0.01 to 0.05% Al, 0.005 to 0.02% N, and the balance Fe with unavoidable impurities. When manufacturing the cold-worked article by subjecting the base steel material to a plural times of cold-working steps, this manufacturing method includes applying prestrain-working to the cold-worked article which has been finally cold-worked, in a direction of reducing shear strain at a part on which the maximum shear strain is formed, prior to the final cold-working step.
