Abstract

An improved nickel-chromium-iron alloy is provided, which comprises up to about 5% of hafnium-containing particles. In one embodiment, an improved creep resistant castable oxide dispersion strengthened nickel-chromium-iron alloy comprises up to about 5% of hafnium, with at least part of the hafnium being present as finely dispersed oxidized particles. Further embodiments of the improved alloy can comprise additionally up to about 15% by weight aluminum. The alloy is particularly useful in the production of creep resistant tubes and castings, for example, for the petrochemical market.
