HAYNES®214 alloy
HAYNES® 214® alloy (UNS N07214) is a nickel – chromium-aluminum-iron alloy, designed to provide the optimum in high-temperature oxidation resistance for a wrought austenitic material, while at the same time allowing for conventional forming and joining. Intended principally for use at temperatures of 1750°F (955°C) and above, 214® alloy exhibits resistance to oxidation that far exceeds virtually all conventional heat-resistant wrought alloys at these temperatures. This is attributable to the formation of a tightly adherent Al2O3-type protective oxide scale, which forms in preference to chromium oxide scales at these high temperatures. At temperatures below 1750°F (955°C), 214® alloy develops an oxide scale which is a mixture of chromium and aluminum oxides. This mixed scale is somewhat less protective, but still affords 214® alloy oxidation resistance equal to the best nickel-base alloys. The higher temperature Al2O3 – type scale which 214® alloy forms also provides the alloy with excellent resistance to carburization, nitriding and corrosion in chlorine-bearing oxidizing environments.
Application HAYNES® 214® alloy combines properties which make it very suitable for service in relatively low-stress, high temperature oxidizing environments, where the utmost in resistance to oxidation or scale exfoliation is needed. Its resistance to such environments persists to temperatures as high as 2400°F (1315°C), although strength limitations may apply. Applications can include “Clean Firing” uses such as mesh belts, trays and fixtures for firing of pottery and fine china, and the heat treatment of electronic devices and technical grade ceramics. In the gas turbine industry, 214® alloy is used for foil construction honeycomb seals, combustor splash plates, and other static oxidation - limited parts. The automotive industry has applications for 214® alloy in catalytic converter internals, and it is used as a burner cup material in auxiliary heaters for military vehicles. In the industrial heating market, 214® alloy is used for highly specialized applications such as refractory anchors, furnace flame hoods, and rotary calciners for processing chloride compounds. It is also used for parts in high temperature chlorine-contaminated environments, such as hospital waste incinerator internals.

HAYNES®244 alloy
HAYNES® 244® Alloy offers a higher maximum use temperature than other low thermal expansion alloys currently available, including a 100-200°F (55-110°C) improvement over HAYNES® 242® alloy. The alloy is age-hardenable by formation of Ni2 (Cr,Mo,W) domains, which are structurally similar to the strengthening domains in 242® alloy. Judicious alloying with tungsten increased the thermal stability of these domains and lowered the coefficient of thermal expansion. Other important properties such as oxidation resistance and low-cycle fatigue performance are comparable or better than those of 242® alloy.

HAYNES®263 alloy
HAYNES® 263 alloy (UNS N07263) is an age-hardenable nickel-cobalt-chromium-molybdenum alloy designed specifically to combine good age-hardened strength properties with excellent fabrication characteristics in the annealed condition. HAYNES® 263 alloy exhibits excellent intermediate temperature tensile ductility, and is not normally subject to strain age cracking problems common for gamma prime strengthened alloys. Its strength at elevated temperature is not quite as high as materials such as HAYNES® 282® alloy, Waspaloy alloy, or R-41 alloy. However, it is much easier to form or weld than Waspaloy alloy and R-41 alloy. Because HAYNES® 282® alloy exhibits superior tensile, creep-rupture, and low cycle fatigue strength than HAYNES® 263 alloy and has significantly greater fabricability than Waspaloy and R-41 alloys, it is replacing HAYNES® 263 alloy in many applications. HAYNES® 263 alloy is normally used for applications up to about 1650°F (900°C). Its oxidation resistance is comparable to that for other gamma-prime-strengthened superalloys.
Application HAYNES® 263 alloy combines properties which make it suitable for a variety of fabricated component applications in both aircraft turbine engine and industrial turbine applications. These include low-temperature combustors, transition liners, and some ring components.

HAYNES®282 alloy
HAYNES® 282® alloy (UNS N07208) is a, 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. The excellent creep strength in the temperature range of 1200 to 1700°F (649 to 927°C) surpasses that of Waspaloy alloy, and approaches R-41 alloy without sacrificing weldability.
Application The features of HAYNES® 282® alloy make it suitable for critical gas turbine applications found in the combustors, turbine and exhaust sections, and nozzle components. Fabrication methods commonly employed include sheet and plate fabrications, seamless and flash butt-welded rings, closed die forgings and components directly machined from bar and heavy plate blanks. In industrial gas turbines, HAYNES® 282® alloy is defining performance standards for combustors and transition sections, and other hot-gas-path components requiring exceptional creep life and low cycle fatigue (LCF) resistance. Automotive turbocharger applications, such as seals and high temperature springs, benefit from the superior high-temperature properties. HAYNES® 282® alloy is also a strong candidate for use in Advanced Ultrasupercritical (A-USC) boiler and steam turbines, Supercritical CO2 power cycle, and concentrating solar power plant, where creep life is required to surpass 100,000 hours at 14.5 ksi (100 MPa) at 1400°F (760°C).
