HAYNES® 244® alloy
Principal Features
HAYNES® 244® alloy is a new Ni-Mo-Cr-W alloy developed for static parts in advanced gas turbine engines which require low thermal expansion at temperatures up to 1400°F (760°C). It 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.

Low Cycle Fatigue
HAYNES® 244® alloy exhibits excellent low cycle fatigue properties at elevated temperature. Results shown below are for strain-controlled tests run in the temperature range from 800 to 1400°F (425 to 760°C). Samples were machined from plate. Tests were run with fully reversed strain (R=-1) at a frequency of 20 cpm (0.33 Hz).

Oxidation Resistance
HAYNES® 244® alloy exhibits very good oxidation resistance at temperatures up to 1400°F (760°C), and should not require protective coatings for continuous or intermittent service at these temperatures. The alloy is not specifically designed for use at higher temperatures, but can tolerate short-term exposures.

Heat Treatment
HAYNES® 244® alloy is furnished in the annealed condition, unless otherwise specified. The alloy is usually annealed in the range of 2000-2100°F (1093-1149°C), depending upon specific requirements, followed by an air cool (or more rapid cooling) before aging. A water quench is recommended for heavy section components. Aging is performed by holding at 1400°F (760°C) for 16 hours, furnace cooling to 1200°F (649°C) and holding for 32 hours, followed by air cool.
Formability
Samples mill annealed and cold worked yielded the following room temperature tensile results:

Welding
HAYNES® 244® alloy can be welded by a variety of processes, including gas tungsten arc and gas metal arc. High heat input processes such as submerged arc and oxyacetalyne welding are not recommended.
Welding Procedures
Welding procedures common to most high-temperature, nickel-base alloys are recommended. These include use of stringer beads and an interpass temperature less than 200°F (95°C). Preheat is not required. Cleanliness is critical, and careful attention should be given to the removal of grease, oil, crayon marks, shop dirt, etc. prior to welding. Because of the alloy’s high nickel content, the weld puddle will be somewhat “sluggish” relative to steels. To avoid lack of fusion and incomplete penetration defects, the root opening and bevel should be sufficiently open.
Filler Metals
HAYNES® 244® alloy should be joined using matching filler metal. Please contact Haynes International for more information.
Postweld Heat Treatment
HAYNES® 244® alloy is normally used in the fully-aged condition. However, following forming and welding, a full solution anneal is recommended prior to aging in order to develop the best joint and overall mechanical properties.
