Inconel X-750 Alloy UNS N07750 EN 2.4669 Wire, Round Bar, Strip, Sheet
Material Inconel X-750, UNS N07750 is a precipitation hardenable nickel-chromium-iron alloy
containing titanium, niobium and aluminium, exhibiting good corrosion resistance at high
and low temperature and high strength up to 820 °C (1500 °F).
Incone X-750 alloy is characterized by:
● high tensile strength up to 600 °C (1100 °F)
● high creep and rupture strength up to 820 °C (1500 °F)
● high oxidation resistance up to 980 °C (1800 °F)
● excellent mechanical properties in cryogenic environments
● good corrosion resistance at high and low temperatures
and high resistance to stress corrosion cracking
● good welability by resistance and fusion processes
