Nickel-base alloy and articles

An article of manufacture including an alloy comprising:

• up to 0.05 weight percent carbon;
• 27.0 to 31.0 weight percent chromium;
• up to 0.5 weight percent copper;
• 7.0 to 11.0 weight percent iron;
• up to 0.5 weight percent manganese;
• up to 0.015 weight percent sulfur;
• up to 0.5 weight percent silicon;
• at least 58 weight percent nickel;
• and
• incidental impurities;
• wherein the alloy exhibits an ASTM grain size of 3.0 to 9.0 and a uniform grain size distribution;
• wherein chemically etched specimens of the alloy include uniformly distributed intergranular M23C6 carbide precipitates on grain boundaries when observed at 500× magnification by scanning electron microscopy;
• wherein chemically etched specimens of the alloy lack metallographically observable intragranular M23C6 carbide precipitates when observed at 500× magnification by scanning electron microscopy;
• and
• wherein the article is selected from a rod, a bar, a round bar, a round rod, a rectangular bar, a rectangular rod, a hexagonal bar, a hexagonal rod, a forged rectangular long product, and a rolled rectangular long product.
