Nickel Alloy GH2696

Nickel alloy GH2696 is a high-temperature alloy with molybdenum-niobium as the main reinforcing element, which is limited to a long-time service temperature of less than 650°C, but can reach an astonishing 750°C for short-time service. The yield, endurance, and creep strengths of this alloy are quite high, and it also has good high-temperature elastic properties, resistance to gas corrosion, and machining plasticity. However, when it is subjected to long-term aging at 800°C, a large number of rod-like Laves phases precipitate at grain boundaries and within the grain, leading to a significant reduction in its strength and toughness. Therefore, in the use of GH2696 alloy need to pay special attention to the impact of its aging treatment.

Nickel Alloy GH2696

Applications:

Nickel alloy GH2696 is suitable for the manufacture of turbine and compressor fasteners, discs, and working blades for long periods below 650°C. In addition, GH2696 alloy is used in a wide range of engines to make a variety of parts such as quick-release rings, fasteners, springs, pipe fittings, mounts, and brackets.

Normal product forms: bars, sheets, plates, coils, pipes, and forged materials.
