What is "aermet"

AerMet alloy is an ultra-high strength type of martensitic alloy steel. The main alloying elements are cobalt and nickel, but chromium, molybdenum, and carbon are also added. Its exceptional properties are hardness, tensile strength, fracture toughness, and ductility. Aermet is weldable with no preheating needed. AerMet alloy is not corrosion resistant, so it must be sealed if used in a moist environment. AerMet is a registered trademark of Carpenter Technology Corporation.

Three types of AerMet alloys are currently available: AerMet 100 (also known as AerMet-for-Tooling), AerMet 310, and AerMet 340 alloy.

Examples of applications include armor, fasteners, airplane landing gear, ordnance, jet engine shafts, structural members, and drive shafts.
