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 facewhich 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.

Description

technical field [0001] The present patent disclosure relates generally to an alloy for a seal ring of a sealing assembly of machinery and equipment, and more particularly, to an alloy for a seal ring of a seal assembly that is sealed by a pair of seal rings A face-to-face contact relationship with rotation. Background technique [0002] For example, a sealed environment in a machine such as an off-road truck can include high pressures, high speeds, and high deflections between relatively movable parts. A seal assembly for retaining lubricant within a seal cavity and for removing foreign matter from bearing surfaces disposed between relatively moving parts within the seal cavity may include a face seal, wherein the seal is achieved by relatively rotating rigid It is achieved by matching the surface of the material sealing part. [0003] In seals employing two rings in face-to-face contact that rotate in relation to each other, there is an urgent need to economically produce...
