Ferrium® S53® steel (AMS 5922, MMPDS) is a double vacuum melted (VIM/VAR) ultra-high strength and ultra-high strength and corrosion resistant steel. It is used in structural aerospace applications, and in applications where other high-strengths steels, such as 300M and 4340, are typically used but require improved corrosion resistance.
Key benefits include:
- Superior corrosion resistance for eliminating toxic cadmium plating
- High strength and toughness for lightweighting or increased torque / power density
- Enhanced thermal stability for high temperature applications
- High hardenability for robust thermal processing
New applications for S53 are frequently discovered by designers. Historically, such applications typically include:
- Flight critical aerospace components, such as landing gear
- Flight critical components on orbital class rocket programs
- Rotorcraft power transmission components, such as rotorshafts
- Structural components for the energy industry
