What is Inconel Alloy751?
Inconel Alloy 751 is a precipitation hardenable nickel-chromium alloy primarily used in high temperature applications such as exhaust valves in internal combustion engines.
Inconel Alloy 751 (UNS N07751) has similar physical, mechanical and corrosion resistance properties to Inconel X-750, but it is an improved version of Inconel The temperature can reach about 870℃. The alloy is strengthened by Al, Ti and Nb and has good corrosion resistance, oxidation resistance and high hot hardness. It has an average corrosion rate of 4.31 g/dm^2/h and is resistant to exhaust stream impurities such as sulfur, bromine and chlorine.
In addition, the heat treatment process of Inconel Alloy 751 has also been optimized, and the heat treatment time has been shortened from the original 18 hours to 9 hours, improving production efficiency. Due to its high high-temperature strength, excellent high-temperature corrosion resistance and wear resistance, this alloy has been used abroad to manufacture valves and other parts for high-load internal combustion engines.
