Abstract: PROBLEM TO BE SOLVED: To provide non-heat treated forgings having high strength and high toughness. SOLUTION: Steel having a composition in which respective contents of C, Si, Mn, Al, N, V, Nb, Mg, Zr, Cr, Ni, Mo, Cu, Ti, B, S, Pb, Ca and Bi are specified is bar-rolled and then cooled, without delay or after reheating, from a temperature between 900 deg.C and 1,350 deg.C down to a temperature between room temperature and 300 deg.C at a rate of (15 to 60) deg.C/sec to form forging steel having a mainly martensitic structure.  When this forging steel is hot-forged, hot forging where the steel is heated to a temperature between the Ac3 point and 900 deg.C and worked at >=0.3 logarithmic strain is carried out at least one or more times at a temperature between the upper limit of unrecrystallization temperature and 700 deg.C, and then cooling is performed through the temperature region from the Ar3 point to 300 deg.C at a cooling rate (CR) represented by inequality (6ε+12) deg.C/sec<=CR<=60 deg.C/sec (where ε is logarithmic strain applied in the unrecrystallization temperature region) to obtain a fine martensitic structure of <=10 μm average grain size.
