4340 Steel Data Sheet

4340 alloy steel also known as aisi 4340 is a low alloy steel with high toughness in an annealed state.

4340 steel data sheet.

Use 4340 alloy steel for power transmission and structural applications that involve extreme impact heat and wear. Due to e 4340 s high alloy content it obtains a uniformed hardness by heat treatment. Download certificates from activity after your order ships. Sae aisi 4340 steel is usually used in places where severe conditions exist and heavy parts requiring high strength and can be widely used as billet bar bar forging sheet pipe and welding wire.

The high fatigue strength makes e4340 ideal for highly stress parts as it maintains it s strength and hardness at elevated temperatures. Other sizes may be available. For technical drawings and 3 d models click on a part number. Typical applications include bolts screws and other fasteners.

Aisi 4340 steel can also be produced as light plates and castings. Certificates with a traceable lot number are available for these products.
