Principal Features<\/h2>\n\n\n\n

HAYNES\u00ae<\/sup>\u00a0X-750 (UNS N07750) alloy is an age-hardenable, nickel-based superalloy with a very good strength at temperatures up to about 1600\u00b0F (870\u00b0C). It is widely used as a wrought material for forged and fabricated parts in aerospace and industrial applications. Its strength is somewhat less than that for HAYNES\u00ae<\/sup>\u00a0718 alloy up to about 1400\u00b0F (760\u00b0C), and lower than that for HAYNES\u00ae<\/sup>\u00a0R-41 alloy at higher temperatures. Alloy X-750 can be cold-formed in the annealed condition, and may also be hot-formed at temperatures of about 1900\u00b0F (1040\u00b0C) or above. Weldability is somewhat limited by susceptibility to strain age-cracking under conditions of heavy restraint. The alloy exhibits good resistance to oxidizing combustion gas environments at temperatures up to about 1600\u00b0F (870\u00b0C).<\/p>\n\n\n\n
