E4340 is a highly alloyed, electric-furnace processed; vacuum degassed grade, which conforms to the rigid aircraft standards of AMS-2301. It contains approximately 0.8% chromium, 1.8% nickel, and 25% molybdenum. The combination of these elements assures deep and uniform hardness when heat-treated, particularly when oil quenched. It possesses exceptional ductility and toughness and remarkably high fatigue strength, snaking E4340 the steel to use for highly stressed parts operating under heavy-duty conditions. It also maintains its excellent strength and hardness while functioning under extremely elevated temperatures.
E4340 finds its most typical use in highly stressed parts that must operate under severe conditions. It is commonly used in the aircraft and missile industries.
