PWA-S-5662 - Pratt & Whitney Nickel 718 Bar & Forging Specification
The Pratt & Whitney Aerospace Material Specification, which defines requirements for producing and inspecting Nickel Alloy 718 (INCONEL 718) in bars, forgings, and rings, is PWA-S-5662. It has similarities with the AMS 5662 specification, so there would be no difference in terms of mechanical properties, heat treatment, as well as certification.
Overview of PWA-S-5662
Nickel Alloy 718 is an austenitic, precipitation hardenable nickel-chromium alloy for high temperature properties, oxidation resistance, and fatigue strength at both high and low temperatures.
The PWA-S-5662 specification ensures strict control of:
- Chemical composition per Pratt & Whitney design limits
- Solution and age heat treatment cycles
- Mechanical property verification (tensile, yield, elongation, and hardness)
- Grain size, cleanliness, and non-destructive testing
PWA-S-5662 and Pratt & Whitney LCS Specifications
Laboratory at Control Source (LCS) is a quality classification for Pratt & Whitney’s suppliers to follow when sourcing material. Fighter Jet Metals sources material from LCS approved manufacturers.
