Characteristics. It is a low-alloy steel containing chromium and molybdenum and nickel as strengthening agents. The steel has good strength and toughness, hardenability and overheat resistance stability, also high susceptibility of flake formation and temper brittleness. Its poor weldability requires high temperature preheating and stress relieving, before and after process.
AISI 4340 Heat Treatment. AISI 4340 alloy steel is heat treated at 830°C (1525°F) followed by quenching in oil. AISI 4340 Forging. AISI 4340 alloy steel is forged at 427 to 1233°C (1800 to 2250°F). AISI 4340 Cold Working. AISI 4340 alloy steel can be cold worked using all conventional methods in the annealed condition. It has high ductility
