AMS 2241 – Composition, Properties, and Uses

AMS 2241

Stainless steel alloys are widely used in various industries because of their unique properties, making them resistant to corrosion, heat, and wear. One of the most versatile types of stainless steel is AMS 2241, a precipitation-hardening alloy with excellent mechanical properties, toughness, and a high strength-to-weight ratio. This blog post aims to provide an overview of AMS 2241, including its composition, physical and mechanical properties, uses, hardness, and heat treatment methods.

AMS 2241 Composition

AMS 2241 is precipitation-hardening stainless steel in the 17-4 PH series. Its composition includes about 15-17.5% chromium, 3-5% nickel, 3-5% copper, and 0.05-0.50% carbon, among other elements. This alloy’s copper and carbon content contributes to its strength and durability. Furthermore, AMS 2241 has a low carbon content, which makes it less prone to intergranular corrosion, a common problem in some stainless steel alloys.

AMS 2241 Physical Properties

AMS 2241 has a density of 7.75 g/cm³, which is relatively high compared to other stainless steel alloys. It also has a melting range of 1400-1450°C, making it suitable for high-temperature applications. Its electrical conductivity is about 2% IACS (International Annealed Copper Standard), which is lower than pure copper but higher than aluminium. AMS 2241 has a coefficient of thermal expansion of 10.8 µm/m°C, which means it expands 10.8 micrometres per meter for every Celsius degree increase in temperature.

AMS 2241 Mechanical Properties

AMS 2241 has excellent mechanical properties, making it suitable for various industrial applications. Its ultimate tensile strength ranges from 1000 to 1250 MPa, depending on the heat treatment condition. Its yield strength can go as high as 1100 MPa, while its elongation at break is around 10-15%. The hardness of AMS 2241 can reach up to 40 HRC (Rockwell hardness scale), making it one of the toughest stainless steel alloys.

AMS 2241 Uses

AMS 2241 is used in various industries that require high strength, toughness, and wear resistance. Some of its common applications include aerospace components, medical equipment, automotive parts, firearms, and oil and gas drilling equipment. It is also used in the production of golf club heads, knife blades, and marine hardware. AMS 2241 can withstand harsh environments and extreme temperatures, making it a popular choice for industrial and commercial use.

AMS 2241 Heat Treatment

AMS 2241 can be heat treated using various methods to enhance its mechanical properties and toughness. This alloy’s most common heat treatment process is ageing, which involves heating the material at a specific temperature for several hours and then cooling it to room temperature. This process can increase the strength and hardness of AMS 2241 without sacrificing its ductility and toughness. Other heat treatment methods for AMS 2241 include annealing, hardening, and tempering, depending on the desired properties and application.


AMS 2241 is a versatile stainless steel alloy with excellent mechanical properties, toughness, and corrosion resistance. It’s unique composition and physical properties make it suitable for various industrial applications, from aerospace to oil and gas drilling. AMS 2241 can be further enhanced through proper heat treatment methods to achieve specific properties for different uses. Overall, this alloy is a reliable and cost-effective option for industries that require high-performance materials that can withstand harsh environments and extreme conditions.
