What Is 4340 Steel?
4340 tool steel is a high-strength, low-alloy steel that contains chromium, molybdenum, nickel, and a small amount of carbon. It is a versatile material that can be used for a wide range of applications that require high strength and toughness.
The addition of chromium, molybdenum, and nickel provides enhanced hardenability, toughness, and wear resistance compared to other types of steel. This allows 4340 steel to be heat-treated to high strength levels while maintaining good ductility and impact resistance.
4340 steel is typically supplied in the annealed condition and is machinable, but it is generally more difficult to machine than other steels due to its high strength and toughness. It is commonly used in the aerospace, defense, and automotive industries, as well as in industrial and manufacturing applications.
