Emerging Technologies

SolarReserve imgThe ever increasing demand for clean energy generation has led to the development of several emerging technologies that need high-temperature alloys for demanding operating conditions. The highly recognizable high-temperature HAYNES® alloys are widely used in traditional power generation, aerospace, chemical processing, and several other industries. With the advent of emerging technologies in this developing energy market, several of Haynes International’s commercially available and newly developed alloys are being used or considered.

ET NuclearThe emerging energy field encompasses within the three key power generation markets: fossil, renewables, and nuclear. In the fossil power generation market, HAYNES® alloys are being used or considered for advanced ultra-supercritical power plants, coal gasification, gas separation technologies for oxycombustion and syngas production, gas-to-liquids, and use of supercritical-CO2 power cycles for energy generation.  Among the renewables, HAYNES® alloys are used and considered for fuel cells, concentrated solar power, thermoacoustic engines, sterling engines, geothermal, waste fuels, and waste- and biomass-to-energy.

In addition, HAYNES® alloys are being considered for the advanced, gas-cooled nuclear reactors and next-gen, molten salt nuclear reactors. As the applications in this field continue to evolve, our metallurgists can assist in the alloy selection process and provide technical support for your application.

Our Emerging Technologies Alloys:

HASTELLOY® N alloy
HASTELLOY® N alloy has good resistance to aging and embrittlement and good fabricability. It has excellent resistance to hot fluoride salts in the temperature range of 1300°F to 1600°F (705°C-870°C).

HAYNES® 214® alloy
HAYNES® 214® alloy is a nickel-chromium-aluminum-iron alloy designed to provide the optimum high-temperature oxidation resistance for a wrought material, while at the same time allowing for conventional forming and joining. This alloy offers outstanding oxidation resistance to 2300°F (1260°C) and is used in demanding oxidation-limited parts. 

HAYNES® 230® alloy
HAYNES® 230® alloy is a nickel-chromium-tungsten-molybdenum alloy that offers the best combination of high- temperature strength, resistance to oxidizing environments up to 2100°F (1149°C) for prolonged exposures, excellent long-term thermal stability, and fabricability of any major high-temperature alloy. 

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. It possesses a unique combination of creep strength, thermal stability, weldability, and fabricability not found in currently available commercial alloys. This new alloy has excellent creep strength in the temperature range of 1200 to 1700°F (649° to 927°C), surpassing that of Waspaloy alloy and approaching that of R-41 alloy. 

HAYNES® 617 alloy
HAYNES® 617 alloy is widely used in gas turbines for combustion cans, ducting and transitions.

HAYNES® 625 alloy
HAYNES® 625 and 625SQ® alloys are used in wide variety of aerospace components. The 625SQ® alloy grade offers improved LCF properties for bellows type applications.

HAYNES® HR-120® alloy
HAYNES® HR-120® alloy offers very good creep strength to 1800°F (980°C), together with good resistance to several industrial environments (e.g. excellent carburization and very good sulfidation and oxidation resistance). This economical alloy has found use in applications as an upgrade from 330 alloy, 800H alloy and stainless steels.

HAYNES® HR-160® alloy
HAYNES® HR-160® alloy has outstanding resistance to sulfidation and other high-temperature aggressive environments. Used in waste incineration, boiler, high-temperature reaction vessel and rotary calciner applications.HAYNES® HR-160® alloy has outstanding resistance to sulfidation and other high-temperature aggressive environments. Used in waste incineration, boiler, high-temperature reaction vessel and rotary calciner applications.

HAYNES® HR-224® alloy
HAYNES® HR-224® is new alloy with excellent oxidation resistance and improved fabricability and weldability compared to HAYNES® 214® alloy.

HAYNES® HR-235™ alloy
HAYNES® HR-235™ is a high-chromium, copper-bearing nickel alloy that has excellent resistance to metal dusting in carbonaceous high-temperature environments. Potential uses include applications in petrochemical production and syngas plants. Similar to other nickel-based corrosion resistant alloys, the alloy is readily fabricated and welded.
