GTD 222

1. Introduce – Cast Ni-based precipitation-hardened alloy used in land-based gas turbine engines Developed by GE to replace the Co-based alloy FSX-414 as the material for the second- and third-stage nozzles (vane) in gas turbines Achieves high-temperature strength through γ’ precipitation hardening and solid solution hardening, and exhibits excellent corrosion and oxidation resistance due to a chromium content of approximately 22% – Excellent castability and weldability * GTD 222 vs. GTD 111 √ GTD 111: An alloy for components requiring high-temperature strength and creep resi...
