Description of Nickel 901 Flanges

Nickel 901 Flanges are a type of flange made from Nickel 901 alloy, which is a high-strength nickel-iron-chromium alloy. These flanges are designed to be used in applications that require excellent corrosion resistance, high-temperature strength, and good oxidation resistance. Nickel 901 is a precipitation-hardening alloy that exhibits exceptional mechanical properties even at elevated temperatures.

The construction of Nickel 901 Flanges involves a forging process, which ensures their strength and durability. The alloy is heated to a specific temperature and then shaped into the desired flange form using high-pressure dies. This forging process helps to refine the microstructure of the alloy, resulting in improved mechanical properties.

Alloy 901 Flanges typically have a raised face design, which means that the sealing surface of the flange is raised above the bolting circle.
