AISI 4340 (E4340) per AMS 6359 - Plate - benedict-miller
Aircraft Quality 4340 per 6359 Hot Rolled Plate. SAE 4340 Chromoly steel is ideal for parts requiring critical harden-ability and high strength metal. For example, gears and aircraft parts which operate under highly stressed, severe conditions perform exceptionally when made from 4340 AQ metal.
AISI 4340 alloy steel can be cold worked using all conventional methods in the annealed condition. It has high ductility. Annealing. AISI 4340 alloy steel is annealed at 844°C (1550°F) followed by cooling the furnace. Tempering. AISI 4340 alloy steel should be in the heat treated or normalized and heat treated condition before tempering.
4340 steel is a low alloy steel that contains Nickel, Chromium and Molybdenum as strengthening agents. 4340 can also be hardened through heat treatment. Flame and induction hardening is the type of heat treatment that works with 4340. 4340 offers better hardenability and improved impact toughness over 4140. Alloy 4340 can obtain deep hardenability.
