As a leading Chinese Inconel alloy supplier, AEETHER manufactures and produces different sizes of Inconel Alloy X-750 fittings. INCONEL® alloy X-750 (UNS N07750 / W.Nr. 2.4669) is a precipitation-hardenable nickel-chromium alloy used for its corrosion and oxidation resistance and high strength at temperatures to 1300°F. Although much of the effect of precipitation hardening is lost with increasing temperature over 1300°F, heat-treated material has useful strength up to 1800°F.
