Is there a relationship between hardness and toughness in 4140 steel?

A tempering temp. of 1,000 F min. gives a very good balance.

Also, there are other factors that can come into play, so one must be careful about any hardness:toughenss relationships one wants to make. In short, if toughness is important, you should probably perform a test to insure the steel has adequate toughness, particular with a steel that has been hardened by quench and tempering, and particularly with 4140.
