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.

Key Features of AISI 4340 Steel

• High strength and toughness after heat treatment.
   
• Excellent fatigue resistance and impact strength.
   
• Good ductility and wear resistance.
   
• Machinable and weldable with proper procedures.
   
• Maintains strength at elevated temperatures.

You can count on AISI 4340 steel when your components must perform reliably under shock loads and high stress.
