WebSteel 4340 is usually normalized at 1500 °F (815 °C) +/- 50 °F (10 °C). Furthermore, the standard hardening temperature is 1500-1550 °F (815-845 °C), followed by tempering for stress relief. After tempering, flame or induction hardening will produce material with Rc 50, while nitriding will produce Rc 60.
WebMachinability is the ease with which a metal can be machined. It is represented in percentage relative to a reference metal. A smaller value means the metal is harder to machine.
