AMS 4034 Uses

One of the most common uses of 4034 AMS is in manufacturing aircraft components, especially for structures subjected to high-stress levels. It is also used to construct turbine engine parts, fasteners, and gears. Steel is versatile, so it can be employed in various applications where strength and toughness are critical.

AMS 4034 Hardness

AMS 4034 is measured using a Rockwell C scale, and the hardness range is around 32-42 HRC. It is important to note that the hardness level mainly depends on the heat treatment and processing conditions used.

AMS 4034 Heat Treatment

Speaking of heat treatment, AMS 4034 uses heat treatment to enhance its physical and mechanical properties. The heat treatment process begins with annealing, which relieves the internal stresses induced during machining. The steel is then quenched, heated again, and finally tempered to achieve the desired hardness, strength and endurance required for any application.

AMS 4034 Density

The topic of AMS 4034 Density may seem technical and dry, but understanding this standard measurement is crucial in many industries. The AMS 4034 standard pertains to the density of aluminium alloy 2024-T3, a popular material for aerospace applications due to its high strength-to-weight ratio. Density, or mass per unit volume, is a key factor in determining the performance and functionality of aerospace components. By adhering to the AMS 4034 standard for density, manufacturers can ensure that their products meet the rigorous requirements of the aerospace industry. So, while it may not be the most exciting topic, the importance of AMS 4034 Density must be balanced.


AMS 4034 is low-alloy steel with excellent strength, corrosion resistance, and toughness. The steel’s composition and properties make it perfect for various industrial applications, such as aircraft components, turbine engine parts, and fasteners.
