Hardness of Heat Treated 4140 Metal and Metallurgy

Heat Treatment. Inspection of a Jominy chart for 4140, which can be found in the SAE handbook, shows that for a Jominy distance of 5, the lower hardness limit is Rc 51 and the upper limit is Rc 59. Since the 90% martensite hardness of Rc 51 lies within the upper and lower hardness limits, the 3/4" bar will fully harden to the center.
