| description | A method of producing a forged steel part is disclosed to include providing a steel billet having a composition including 0.25 - 0.40 wt.% C, 1.50 - 3.00 wt.% Mn, 0.30 - 2.00 wt.% Si, 0.00 - 0.150 wt.% V, 0.02 - 0.06 wt.% Ti, 0.010 - 0.04 wt.% S, 0.0050 - 0.0150 wt.% N, 0.00 - 1.00 wt.% Cr, 0.00 - 0.30 wt.% Mo, 0.00 - 0.003 wt.% B, and a balance of Fe and incidental impurities. The method may further include heating the steel billet to an austenization temperature of approximately 1150 degrees C to 1350 degrees C, hot forging the steel billet to form the steel part, and controlled air cooling the forged steel part after the hot forging. The method may still further include induction heating select portions of the forged steel part after the controlled air cooling to increase the hardness of the select portions of the forged steel part, followed by quenching and tempering before the final machining. |
