GH3128 (GH128) Nickel-based alloy

>> GH3128(GH128)
Overview of GH3128 characteristics and application fields:
The alloy is a nickel-based alloy solid solution-strengthened with tungsten and molybdenum and grain boundaries reinforced with boron, cerium and zirconium. It has high plasticity, high lasting creep strength, good oxidation resistance and stamping and welding properties. Its comprehensive performance is better than similar nickel-based solid solution alloys such as GH3044 and GH3536. It is suitable for manufacturing combustion chamber flame tubes, afterburner casings, regulator plates and other high-temperature parts of aeroengines that operate at 950°C for a long time.

GH3128 metallographic structure:
The alloy has a single-phase austenite structure in the solid solution state and contains a small amount of fine and evenly distributed TiN and M6C.
GH3128 process performance and requirements:
1. The furnace temperature for steel ingot forging should not be higher than 700°C, and the final forging temperature should be higher than 900°C. 2. The average grain size of the alloy is closely related to the deformation degree and final forging temperature of the forging. 3. Alloys can be welded by argon arc welding, spot welding, seam welding and other methods.
