Nickel Alloy WASP

  • Nickel Alloy WASP
  • General Characteristics

    WASP is a nickel- base alloy with excellent high temperature strength and good resistance to oxidation at a temperature up to 1200 °F. WASP has higher stability and strength ranges than those available for alloy 718. WASP can be heat treated in three-steps: solution treatment, stabilization and age-hardening.
