Heat Treating 4140 steel FAQ anvilfire How-to.

1) 4140 is an OK die steel but is not recommended for radical shaped dies such as narrow fullering, crown and so on. 2) Fully hardened 4140 ranges from 54 to 59 HRC. But it should be tempered for any heavy use. 3) Tempering recommendations from the ASM heat treaters guide for 4140-4142 is a minimum of 400°F.

42CrMo4 - steel-navigator

42CrMo4 is a steel for quenching and tempering, which has a good combination of strength and toughness in the quenched and tempered condition. After the oil quenching, the steel will be through hardened up to ø60 mm bar diameter. The microstructure of larger dimensions is not fully martensite. The steel is applicable to induction hardening.
