Abstract
A wear and oxidation resistant nickel-base alloy, exhibiting resistance to thermal cracking in high-stress elevated temperature environments, comprises, in weight percentages based on total alloy weight: 53 to 67 nickel; 20 to 26 chromium; and 12 to 18 tungsten. The alloy optionally further comprises, in weight percentages based on total alloy weight, at least one of: up to 3 cobalt; up to 3 molybdenum; up to 6 iron; 0.1 to 0.5 manganese; 0.1 to 0.7 silicon; 0.1 to 0.6 aluminum; and less than 0.05 carbon. Components of a seamless tube manufacturing apparatus fabricated from the alloy also are provided. The components may be, for example, tools for one of a piercing mill, a high mill, and a rotary expander, such as piercer points, piercing mill guide shoes, rotary expander guide shoes, reeler guide shoes, and high-mill plugs.
