Haynes International produces alloys that enable the successful use of many power generation technologies. Our portfolio of HAYNES® high-temperature alloys are designed to resist oxidation, sulfidation, carburization and to cover a broad variety of challenging environments.
The largest power generation applications focus on Industrial Gas Turbines. Because of their combination of high-temperature strength, resistance to oxidation, formability, and weldability, HAYNES® alloys are found in burners and injectors, combustion liners, transitions ducts, and exhaust components. These same characteristics make these alloys attractive in Advanced Ultra-supercritical Steam, Supercritical CO2, Sterling Engines, Concentrated Solar Power (CSP) plants, fuel cells, and other unique power generation methods.
Industrial Gas Turbines
In thousands of industrial gas turbines all over the world, HAYNES® and HASTELLOY® alloys are quietly and reliably working to provide electrical power, transportation and fluid/gas transmission that keep the global economy running. From large frame engines providing hundreds of megawatts of power to mechanical compressors for pipelines to recuperated microturbines supplying combined heat and power, gas turbine combustion systems need materials with the high strengths needed to control shape at high temperatures for thousands of hours. HAYNES® alloys fulfill that need in ways few other materials can match. With very good ductilities in most of these alloys, many complex fabrications have been made. For more information, click here.

Advanced Ultrasupercritical (A-USC) Steam Power
On nearly every continent on the global, A-USC programs have been initiated to find a way to drastically enhance the efficiency of coal-fired power and reduce emissions. All programs seek to increase temperatures and pressures to achieve these goals. In the U.S., a consortium of OEM’s, National Labs, and other industrial organizations have been looking at conditions of 1400°F (760°C) and 36.2MPa (5250 psi) where high-temperature nickel alloys will be necessary. For these programs, HAYNES® 282® alloys is under consideration as one of the highest creep strength and fabricable materials available.
Supercritical CO2 (SCO2)
Like A-USC steam, Supercritical CO2 offers higher power densities and a way to drastically enhance the efficiency with reduced emissions. Operating at 1292°F (700°C), HAYNES® 282® alloys is attractive as one of the highest creep strength and fabricable materials available.
Concentrated Solar Power (CSP) with Thermal Storage
Renewable energy technologies like concentrated solar power offer zero net emissions in operation, and with thermal energy storage via molten salts, can operate for extended hours after sunset. However, the high temperatures and thermally cycling present unique challenges for the high temperature receivers. HAYNES® alloys, like 230® alloy, provide excellent creep strength and oxidation/corrosion resistance necessary to meet the targeted service life for the tubular products.
Our Power Generation Alloys:
HAYNES® 282® alloy
HAYNES® 282® alloy is a new, wrought, gamma-prime strengthened superalloy developed for high-temperature structural applications, especially those in aero and industrial gas turbine engines. Since its introduction in 2005, it has been quickly adopted by many OEM’s for its unique combination of creep strength, thermal stability, weldability, and fabricability not available in other commercial alloys. The excellent creep strength in the temperature range of 1200 to 1700°F (649° to 927°C) surpasses that of Waspaloy alloy and approaches that of R-41 alloy. The features of this alloy make it suitable for critical gas turbine applications, such as combustion liners, transition pieces, forged rings and cases, exhaust and shroud structures, and other hot gas path components.
HAYNES® 292® alloy
HAYNES® 292® alloy is a wrought, gamma-prime strengthened superalloy for high-temperature applications such as cases and rings used in aero and industrial gas turbine engines. This new alloy can be readily fabricated and welded and is expected to offer superior low-cycle fatigue (LCF) strength, creep strength, and oxidation resistance compared to Waspaloy and other wrought gamma-prime strengthened alloys.
HAYNES® 230® alloy
HAYNES® 230® alloy is the premium solid-solution, turbine hot gas path alloy available today. It offers a better combination of high-temperature strength,
resistance to prolonged exposures to oxidizing environments up to 2100°F (1149°C), excellent long-term thermal stability, and fabricability than any commercially
available high-temperature alloy. It is used for combustion cans, transition ducts, flame holders, turbine shrouds, thermocouple sheaths, and other important gas
turbine components.
HAYNES® 233® alloy
HAYNES® 233® alloy is a new, superior turbine hot gas path alloy with outstanding creep strength coupled with excellent oxidation resistance at temperatures up to 2100°F (1149°C) – a combination of properties never before achieved in a readily fabricable alloy. The alloy achieves its exceptional oxidation resistance via formation of a protective alumina scale, while the high creep strength is a result of solid-solution and carbide strengthening. Finally, the alloy can be readily fabricated using conventional methods since it exhibits good hot workability, cold formability, and weldability. These capabilities offer the highest performance yet achieved in metallic aerospace and industrial gas turbine combustors, transition pieces, rings and casts, and other hot structures.
HASTELLOY® WR-66® alloy
HASTELLOY® WR-66® alloy has excellent sliding wear resistance and corrosion resistance in aqueous corrosion media. Corrosion resistance and ductility vastly superior to commonly used CoCr (Cobalt-Chromium) alloys in weld overlay form, while maintaining comparable resistance to sliding wear and galling.
HAYNES® 214® alloy
HAYNES® 214® alloy is the most oxidation resistant, wrought nickel alloy commercially available, offering outstanding resistance to 2300°F (1260°C) via formation of a highly protective alumina scale. Strengths are very good at intermediate temperatures to 1650°F (900°C), and the alloy can be conventionally formed and
joined. This alloy is used in demanding, specialized gas turbine parts, such as honeycomb seals, combustor.
HAYNES® 188 alloy
HAYNES® 188 alloy is a cobalt-nickel-chromium-tungsten alloy that offers excellent high-temperature strength and superior oxidation resistance up to 2000°F (1095°C) and thermal stability. This alloy is used extensively in demanding military and civil aircraft gas turbine engine combustors, transition ducts, and after-burner components.
HASTELLOY® X alloy
HASTELLOY® X alloy has been and continues to be the workhorse alloy for combustion parts in industrial gas turbine applications all over the world. The alloy offers a very good balance of high-temperature strength, oxidation resistance, and fabricability at lower cost than many other materials. This alloy is widely used in
industrial gas turbine and aircraft engine fabricated combustor and exhaust components, such as transition ducts, combustor cans and liners, injector nozzles and spray bars, flame holders, exhaust struts and many other hot gas path components.
HAYNES® HR-120® alloy
This is a solid-solution-strengthened heat-resistant alloy that provides excellent strength at elevated temperature combined with very good resistance to carburizing and sulfidizing environments. Its oxidation resistance is comparable to other widely used Fe-Ni-Cr materials, such as alloys 330 and 800H, but its
strength at temperatures up to 2000ºF (1095ºC) is significantly higher, even in comparison to Ni-Cr alloys. The alloy can be readily formed hot or cold, and is commonly welded using HAYNES® 556® filler wire.
