1 Components HP and IP, High T LP, High T Rotor Diaphram Blades/Nozzles
Casing/Steam Chest LP, High T Rotor Diaphram Blades/nozzles

2 List of Potential Materials HP, High T, Static and Dynamic
Inconel 617 Inconel 625 Inconel 718 Inconel 740 Nimonic 105 Nimonic 115 Nimonic 263 Haynes 230 Haynes 282 U700 U710 U720 Waspaloy ODS-FeCrAl

3 Phase 1 – Disqualifying Factors HP Components – Rotor and Casing
(Ti+Al )< 2.5 Weldability Yes - Inconel 617, Inconel 625, Inconel 718, Haynes 230, Inconel 740, Nimonic 263 No - U700, U710, U720, Waspalloy, Nimonic 105, Nimonic 115, Haynes 282 ODS-FeCrAl Parameter > 25 Larson-Miller Yes - Inconel 617, Inconel 740, Nimonic 263 No - Inconel 625, Inconel 718, Haynes 230 Machinability Inconel 617, Inconel 740, Nimonic 263

4 Phase 2 - Performance Ranking Rotor and Diaphragm
Material Yield Strength Oxidation x 10 Cost x - 5 Total Inconel 617 283 8 10.70 309.5 Inconel 740 608 10 654.5 Nimonic 263 630 6 11.39 633.05

5 Phase 2 - Performance Ranking Casing
Material Yield Strength Oxidation x 5 Cost x - 10 Total Inconel 617 283 8 10.70 216 Inconel 740 608 10 551 Nimonic 263 630 6 11.39 546.1

6 Phase 1 – Disqualifying Factors HP Components – Blades
Weldability N/A Parameter > 25 Larson-Miller Yes - Inconel 617, Inconel 740, Nimonic 263, Nimonic 105, Nimonic 115, U720, Waspaloy, Haynes 282 No - Inconel 625, Inconel 718, Haynes 230 Machinability Yes - Inconel 617, Inconel 740, Nimonic 263,Nimonic 105, Nimonic 115, U720, Waspaloy, Haynes 282 No – U720

7 Phase 2 - Performance Ranking HP Blades
Material Yield Strength Oxidation x 10 Cost x - 10 Total Inconel 617 283 8 10.70 256 Inconel 740 608 10 601 Nimonic 263 630 6 11.39 576.1 Nimonic 105 690 x 11.36 576.4 Nimonic 115 Waspaloy 650 5 10.30 597 Haynes 282 614 10.35 570
