  • Alloy for seal ring, seal ring, and method of making seal ring for seal assembly of machine
    Patent number: 11104978
    Abstract: A seal ring for a seal assembly includes a body and a seal flange. The body is generally cylindrical and extends along a longitudinal axis between a load end and a seal end. The seal flange is disposed at the seal end of the cylindrical body. The seal flange circumscribes the body and projects radially from the body to a distal perimeter of the seal flange. The seal flange includes a sealing face which is annular and disposed adjacent the distal perimeter. The seal ring is made from an alloy that includes between 6 percent and 9 percent by weight of iron, between 1.5 percent and 3 percent by weight of silicon, greater than 14 percent by weight of chromium, and at least 65 percent by weight of nickel.
