HAYNES® 244™ alloy is a new, age-hardenable, nickel-molybdenum-chromium-tungsten alloy with an extended operating temperature range to 1400°F (760°C). This alloy offers improved yield strength and creep rupture strength, versus HAYNES® 242® alloy, as well as a lower thermal expansion. Additionally, the alloy has excellent low-cycle fatigue and good oxidation resistance. The higher strength and lower thermal expansion provides better dimensional control, sealing, and containment characteristics for aero engine designers.
