Abstract

Steel composition contains (in wt.%) 0.12-0.45 C, 0.10-1.00 Si, 0.50-1.95 Mn, 0.005-0.050 Al, 0.004-0.050 Al, 0.004-0.050 Ti, 0-0.60 Cr, 0-0.60 Ni, 0-0.60 Co, 0-0.60 W, 0-0.01 B, 0-0.60 Mo, 0-0.60 Cu, 0-0.050 Nb, 0.10-0.40 V, 0.015-0.040 N, and a balance of Fe. The amount of V x the amount of n is 0.0021-0.0120. 1.6 x the amount of S + 1.5 x the amount of Al + 2.4 x the amount of Nb + 1.2 x the amount of Ti is 0.035-0.140. 1.2 x the amount of Mn + 1.4 x the amount of Ni + 1.1 x the amount of Cu + 1.8 x the amount of Mo is 1.00-3.50. An Independent claim is also included for a process for the production of a drop forged part comprising heating a pre-material made from the above steel composition to a temperature of 1000-1300degrees C, deforming by forging, and cooling the drop forged part obtained to room temperature from 580degrees C at a cooling rate of 0.2-0.6degrees C/s.
