Overview
As a leading supplier & manufacturer in China, AEETHER supply cost-effective Inconel 751 Products.
INCONEL® alloy 751 (UNS N07751) is a precipitation hardenable nickel-chromium alloy, used mainly for the exhaust valves of internal combustion engines. 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 as sulfur, bromine and chlorine.
The hot working range for INCONEL alloy 751 is 1800- 2200°F (980-1205°C). The alloy should be reheated to 2200°F (1205°C) whenever its temperature falls below 1800°F (980°C).
INCONEL alloy 751 is readily machined in the as-hot finished condition. The best procedure is to machine to slightly oversize, precipitation heat treat, then finish to size. A slight permanent contraction (about 0.0003 in/in) takes place during precipitation. Precipitation treated material can be finish machined to fine finishes and close tolerances, and will have good dimensional stability.
