API WI-2366
  • NWI proposed API Summer Standards Conference June 2010 to add a new Group 5 to API 5CRA for:
    • Age hardened nickel based alloys for coupling stock and accessory material.
  • Alloys Include UNS Numbers: N09925, N09935, N09945, N07718, N07716, N07725.
  • For harmonization, WI-2366 coordinated and held alternate meetings with the API 6A718 WG to coordinate development of material requirements for age hardened nickel-based alloys.
