AMS 2301 Alloy Steel – Composition, Properties, and Uses

AMS 2301

AMS 2301 might not be a well-known term to many, but for those in the engineering and manufacturing industries, it is a critical material that is widely used. AMS 2301 is a specification for alloy steel with unique properties and is often used in industrial applications, particularly in the aerospace industry. In this blog post, we will explore the composition, physical and mechanical properties, uses, hardness, and heat treatment of AMS 2301.

What is AMS 2301?

AMS 2301 metal is a type of steel widely used in industries that rely on high-performance materials. This metal is known for its exceptional properties, including its resistance to corrosion, heat, and wear. It can withstand extreme temperatures and is used in applications where other materials cannot perform. The AMS2301 metal is often used in aerospace, power generation, and oil refining, among other industries. Its strength, and unique properties make it a go-to material for demanding applications. Its durability ensures that equipment can withstand heavy usage and stay functional for extended periods. The wide range of applications of AMS 2301 metal highlights its importance in various sectors of the economy.

AMS 2301 Composition

AMS 2301 is a quenched and tempered alloy steel containing low amounts of carbon, manganese, and silicon and high amounts of nickel, chromium, and molybdenum. The composition of AMS 2301 is designed to provide excellent strength, toughness, and fatigue properties, making it ideal for applications in which high-stress resistance is required.

AMS 2301 Physical Properties

AMS 2301 has a density of around 7.85 g/cm³ and a melting point of 1420-1460°C. It has excellent corrosion and oxidation resistance and good ductility, making it an ideal material for applications that require high strength, toughness, and resistance to harsh environments.

AMS 2301 Mechanical Properties

The mechanical properties of AMS 2301 vary depending on the heat treatment and the final application of the material. Its hardness can range from 170 to 237 HBW depending on the type of heat treatment. Its tensile strength ranges from 1110 to 1240 MPa, and its yield strength is 690-780 MPa. AMS 2301 has excellent fatigue resistance and a high endurance limit.

AMS 2301 Uses

AMS 2301 is widely used in aerospace for parts such as turbine disks, compressor blades, and shafts. It is also used in high-performance industrial applications such as steam turbines, pumps, and pressure vessels. Additionally, AMS 2301 is used in the defence industry to manufacture military aircraft parts.

AMS 2301 Hardness

The heat treatment applied to the hardness of AMS 2301 can be affected. As mentioned earlier, its hardness can range from 170 to 237 HBW. The heat treatment process can also improve its wear resistance and increase its fatigue life.

AMS 2301 Heat treatment

AMS 2301 is heat-treated at high temperatures to increase its toughness and strength. Heat treatment involves heating the material to a specific temperature, holding it at that temperature for a specific amount of time, and then quenching it quickly in oil or water to cool it rapidly. Once the material is satisfied, it undergoes a tempering process, which involves reheating it to a specific temperature to relieve some residual stresses and increase its toughness.


In conclusion, AMS 2301 material is a high-strength, low-alloy steel widely used in demanding applications, particularly aerospace and defence industries. Its unique blend of physical and mechanical properties, such as excellent fatigue, toughness, and corrosion resistance, make it an ideal material for high-performance applications. The right heat treatment techniques can further enhance its properties. As industries continue to grow and evolve, the demand for high-performance materials like AMS 2301 will continue to grow.
