Abstract
A nickel-based alloy for forming a seal ring is disclosed. Such seal rings, in use may be static or rotating and may be used in a variety of applications, such as in wheel assemblies of machines. Using the alloy, the seal ring may be manufactured using a centrifugal casting method. The disclosed alloy includes a chromium content greater than at least 13.5% by weight, a boron content less than 3% by weight, a carbon content less than 2% by weight, and nickel content greater than 70% by weight. The nickel alloy may have a carbon plus boron atomic content divided by chromium atomic content less than 1.1. This alloy allows for the rapid cooling of centrifugal casting while maintaining a grain morphology suitable for relatively low leakage and relatively high durability. When the alloy is formulated, the seal ring is formed by centrifugal casting.
