What is AISI 4340 Steel?
AISI 4340 steel is a nickel-chromium-molybdenum alloy steel known for its exceptional toughness, high strength, and superior fatigue resistance. It is one of the most versatile engineering steels used in high-stress components that demand reliability and durability.
It is widely used in components that demand high tensile strength and impact resistance, such as aircraft landing gears, drive shafts, and heavy-duty transmission systems.When properly heat-treated, AISI 4340 develops high core strength and hardness, while retaining superior fatigue and shock resistance, even under severe loading conditions.
