Land-based Gas Turbines
Materials Made for More Megawatts
The path to greater turbine efficiency runs through hotter, more demanding operating conditions. ATI brings decades of superalloy expertise, advanced melting and forging capabilities, and a broad portfolio of heat- and corrosion-resistant materials to land-based gas turbines, helping power producers get more from every machine.
The Aero Engine Advantage. On the Ground.
ATI brings materials expertise developed for some of the hottest, highest-stress environments in aerospace to industrial gas turbines, producing nickel-based superalloys engineered to maintain strength and resist oxidation as temperatures climb.
Big Turbines Need Big Forgings.
ATI pairs advanced nickel alloys with hot-die forging capabilities for large-diameter gas-turbine components, bringing material and manufacturing expertise together for critical rotating applications.
Develop the Alloy. Then Scale It.
Next-generation turbines demand more from materials. ATI's materials scientists develop and optimize advanced high-temperature alloys, backed by melt, forge, roll and testing capabilities that create a pathway from development to production.
More Than the Turbine.
ATI's material portfolio extends beyond the turbine itself into balance-of-plant systems, where heat, pressure and corrosion create different but equally demanding materials challenges.

Heat Meets Centrifugal Force
Turbine disks and other rotating components operate under the combined effects of elevated temperature, high rotational loads and repeated operating cycles. As turbines push toward greater output and efficiency, materials must retain strength and resist fatigue over long service lives.
Forged for Power
ATI combines high-performance nickel-based superalloys with advanced forging expertise to produce large, high-integrity rotating components engineered for demanding land-based turbine service.
Combustion & Hot-Section Components

The Hotter It Burns, the Harder Materials Work
Higher combustion temperatures can improve turbine performance and efficiency, but they subject combustors, transition pieces, housings and ducting to sustained heat, oxidation and thermal cycling.
Alloys That Stay Strong When the Heat Stays On
ATI develops and produces nickel-based alloys specifically engineered for high-temperature strength and oxidation resistance. ATI 617™ alloy, for example, maintains excellent creep-rupture strength and oxidation resistance above 1,800°F and is used in combustion cans, inner housings, ducting and transition liners in land-based gas turbines.

Hold Everything Together While Everything Changes
Large turbine structures experience temperature gradients, thermal expansion and repeated startup and shutdown cycles. Materials must combine high-temperature strength, dimensional stability and resistance to environmental degradation.
Strength Built for the Long Run
ATI's broad nickel-alloy portfolio gives turbine manufacturers material options engineered around different combinations of temperature, strength, fatigue, creep and corrosion resistance, supported by ATI's melt.
