Product Description

A precipitation-hardenable nickel-cobaltchromium alloy with an addition of molybdenum for solid-solution strengthening. The relatively high aluminum content enhances both strength (through greater precipitation hardening) and oxidation resistance. The alloy has high creep-rupture properties at temperatures to about 1740°F (950°C). Used in gas turbines for blades, discs and shafts.

STANDARD PRODUCT FORMS

Round and extruded section.
