INCONEL® alloy 751 (UNS N07751) is a precipitation hardenable nickel-chromium alloy, used mainly for the exhaust valves of internal combustion engines. Its limiting chemical composition is shown in Table 1. The alloy has essentially the same excellent physical, mechanical and corrosion-resistance properties as INCONEL alloy X-750. Some physical constants for INCONEL alloy 751 are shown in Table 2. Its thermal properties correspond closely to those published for INCONEL alloy X-750. In the evaluation of materials for exhaust valve applications, nickel-chromium alloys have performed well in a 1675°F (913°C) lead oxide screening test. INCONEL alloy 751 repeatedly offered good results, with corrosion rates averaging 4.31 g/dm2 /h. Like other nickel-chromium alloys, INCONEL alloy 751 also resists attack by other exhaust stream impurities such assulfur, bromine and chlorine.
