wwwwww..ssppeecciiaallmmeettaallss..ccoomm INCONEL® alloy X-750 (UNS N07750/W. Nr. 2.4669) TTaabbllee 11 - Limiting Chemical Composition, % is a precipitation-hardenable nickel-chromium alloy Nickel (plus Cobalt)70.00 min. used for its corrosion and oxidation resistance and high Chromium14.0-17.0 strength at temperatures to 1300°F. Although much of Iron5.0-9.0 the effect of precipitation hardening is lost with Titanium2.25-2.75 increasing temperature over 1300°F, heat-treated Aluminum0.40-1.00 material has useful strength up to 1800°F. Alloy X-750 Niobium (plus Tantalum)0.70-1.20 also has excellent properties down to cryogenic termperatures. Composition is shown in Table 1. Manganese1.00 max. The economics of INCONEL alloy X-750 coupled Silicon0.50 max. with its availability in all standard mill forms has Sulfur0.01 max. resulted in applications in a wide variety of industrial Copper0.50 max. 0 fields. In gas turbines, it is used for rotor blades and Carbon0.08 max. wheels, bolts, and other structural members. INCONEL 1 Cobalt 1.00 max 5 alloy X-750 is used extensively in rocket-engine thrust 1 chambers. Airframe applications include thrust Determination not required for routine acceptance.
