Abstract Scope 4140 steel is typically either oil or polymer quenched to avoid distortion and cracking. This work is based upon the principle of intensive quenching to achieve higher hardness avoiding quench cracks, whitout the aid of specialized equipment. To achieve this goal a 4140 steel bar was heat treated in an electric muffle and quenched in violently agitated brine to obtain a Grossman H value above 6. The results were above the expected, since the theoretical hardness calculated from the Grossman method for DI and Jominy curve calculation predicts a surface hardness of 58 HRC and the measured surface hardness was above 64 HRC.
