AMS 5800 Nickel Alloy – Composition, Properties, and Uses

AMS 5800

If you have been working in the metals industry, you might have heard of AMS5800. But what is it exactly? In this blog post, we will look closer at AMS5800, its composition, physical and mechanical properties, uses, and how it is heat-treated. By the end of this article, you will better understand this material and its applications.

What is AMS 5800?

AMS 5800 (also known as Nickel Rene 41) is a standard used in the aerospace industry to measure the surface cleanliness of metal parts. This standard specifies the procedures and requirements for testing parts using techniques such as water break, dye penetrant, and contact angle measurements. AMS 5800 ensures that metal parts are thoroughly cleaned and free of contaminants that may negatively affect their performance and longevity. As an expert in the aerospace industry, I highly recommend adhering to AMS 5800 to ensure the highest quality of metal parts.

AMS 5800 Composition

AMS 5800 is a nickel-based alloy that is designed for use in high-temperature environments. Its composition comprises 25% chromium, 20% molybdenum, 5.5% aluminium, and 0.08% carbon. It also contains traces of iron, nickel, silicon, and titanium. This unique composition gives AMS 5800 excellent strength and resistance to corrosion and oxidation.

AMS 5800 Uses

Given its impressive physical and mechanical properties, AMS 5800 finds its way into various applications. For instance, it is commonly used in gas turbine engines for high-temperature components such as combustion chambers, afterburners, and exhaust systems. Similarly, it is also used in aircraft engines for similar purposes.

AMS 5800 Hardness

Another crucial characteristic of the AMS 5800 is its hardness. Heat-treated to achieve a typical hardness range of 39-44 HRC. This range makes it highly wear-resistant, especially in high-pressure and heavy-duty applications.

AMS 5800 Heat Treatment

Heat treatment is a crucial process that enhances the mechanical properties of AMS 5800. There are two heat treatment processes; annealing and ageing. Annealing involves heating the material to 1065°C for an hour, followed by cooling in air to relieve any internal stresses within the material. Ageing, however, involves heating the annealed material to 760°C for sixteen hours, followed by cooling to achieve the desired hardness.


In conclusion, AMS 5800 material is a nickel-based alloy with an outstanding combination of physical and mechanical properties. This material is widely used in high-temperature applications such as gas turbines and aircraft engines due to its resistance to corrosion, oxidation, and wear. One can better use this material for various industrial applications by understanding its composition, properties, and applications.
