What is AMS 2304?

AMS 2304  is a specification developed by the Aerospace Materials Division of the Society of Automotive Engineers (SAE) for producing stainless steel bars and wire used in aircraft applications. This specification sets stringent requirements for the chemical composition, mechanical properties, and overall quality of the material to ensure it meets the demands of the aerospace industry. AMS2304 stainless steel is used in critical applications such as fuel systems, hydraulic tubing, and engine components where failure is not an option. Its superior corrosion resistance, high strength, and durability make it an ideal material for these demanding applications. The development of AMS2304 demonstrates the aerospace industry’s commitment to safety, reliability, and innovation.

AMS 2304 Composition

AMS 2304 is classified under stainless steel’s austenitic F51 / F60/ F61 material grade. It has less than 0.03% carbon, which is responsible for its excellent weldability feature. Besides, it contains high nickel, molybdenum, and chromium, with impressive corrosion resistance properties.

AMS 2304 Physical Properties

This type of steel has excellent physical properties, such as high flexibility and toughness, which make it resistant to breakage at low temperatures. Its density is 7.8 g/cm³, and it has good thermal conductivity, meaning it can quickly transfer heat energy from one point to another without undergoing major distortion or deformation.

AMS 2304 Mechanical Properties

AMS 2304 boasts high tensile strength, which measures a metal’s maximum tensioning capacity before it breaks. It has a yield strength of about 550 MPa and a tensile strength of over 700 MPa. Its elongation is 22%, indicating its excellent flexibility.

AMS 2304 Uses

AMS 2304 is widely used in various demanding applications such as chemical and oil refineries, water treatment and desalination plants, pulp and paper, and pharmaceutical manufacturing plants. It is also useful in structural and architectural applications, road and rail transport, and marine engineering.

AMS 2304 Hardness

The hardness of AMS 2304 depends on its specific heat treatment. Its annealed state has a Brinell hardness of approximately 192 HB. However, when treated to the appropriate conditions, it can achieve impressive hardness levels of up to 320 HB.

AMS 2304 Heat treatment

AMS 2304 can be heat-treated through solution annealing, which involves soaking it in a high-temperature solution, and then quenching it in water or oil. This process enhances its mechanical properties and reduces its susceptibility to stress corrosion cracking.


There is a comprehensive overview of AMS 2304 material and its different properties. It’s a remarkable type of steel famous for its excellent corrosion and chemical resistance. Consider its durability and strength when choosing materials for your next project’s application, especially in harsh conditions.
