AerMet 100 is a martensitic steel alloy characterized by ultra-high strength. The property of this alloy comes directly from the robust crystalline structure that’s a characteristic of almost every martensitic alloy. The main advantages of Steel AerMet 100 are superior fracture toughness and ductility, excellent fatigue and stress corrosion cracking resistance, and high fatigue strength. That said, Steel AerMet 100 is not a corrosion resistance alloy, which means that special care is needed for sealing the parts if they are to be used in wet environments.
Thanks to its excellent mechanical properties, AerMet 100 has widespread use in the military and aerospace applications. More precisely, it is used for manufacturing of armor, fasteners, landing gear, actuators, artillery, ballistic tolerant components, jet engine shafts, structural members, drive shafts and structural tubing. This steel alloy can be used at temperatures of up to 800°F (427°C) and possesses a minimum tensile strength of 280 ksi (1930 MPa) and a minimum toughness of 100 Ksi√ in.
AerMet 100 is considered as an upgrade to AF1410 because it has fewer restrictions and a higher combination of strength and toughness.
Apart from the outstanding mechanical properties, Steel AerMet 100 is characterized by good weldability without preheating, excellent polishability, and it can also be readily formed.
