GTD-222 Superalloy

GTD-222 is an advanced gamma-prime strengthened nickel-based superalloy. Primarily engineered for heavy-duty land-based gas turbines and aerospace structural components, it serves as a high-performance, long-service-life alternative to conventional FSX-414 for turbine nozzle and guide vane applications.

GTD-222 Superalloy Introduction

GTD-222 is an advanced gamma-prime strengthened nickel-based superalloy. Primarily engineered for heavy-duty land-based gas turbines and aerospace structural components, it serves as a high-performance, long-service-life alternative to conventional FSX-414 for turbine nozzle and guide vane applications.

GTD-222 Superalloy Characteristics

STEP 1

Superior Temperature Resistance

GTD-222 delivers approximately 93°C (200°F) improvement in creep resistance and structural integrity compared to FSX-414, ensuring exceptional operational durability for prolonged service in extreme environments at temperatures up to 1000°C.

STEP 2

Chemical Composition

It is produced via vacuum casting and predominantly alloyed with chromium, cobalt, tungsten and titanium, endowing the superalloy with superior hot-corrosion resistance and high-temperature oxidation resistance.

STEP 3

Enhanced Weldability

Unlike earlier turbine nozzle alloys, GTD-222 is easier to repair and weld, reducing maintenance turnaround times.

GTD-222 Superalloy Application

Power Generation: Extensively deployed for second and third-stage nozzles of heavy-duty industrial gas turbines.

Aerospace: Applied to intricate stationary components and thermally stressed guide vanes under rigorous thermal loading conditions.
