GH3536 Alloy Powder
GH3536 alloy powder is a nickel-based superalloy powder used for additive manufacturing applications requiring high strength and corrosion resistance at elevated temperatures. As an advanced powder metallurgy product, GH3536 allows complex geometries to be fabricated using laser or electron beam-based metal 3D printing processes.
GH3536 alloy powder was designed specifically for additive manufacturing, using composition optimization and powder atomization techniques to achieve superior properties compared to conventional nickel superalloys. The key features of GH3536 alloy powder include:
High strength at temperatures up to 760°C (1400°F)
Oxidation and corrosion resistance in harsh environments
Excellent thermal fatigue life and crack growth resistance
Good printability and low porosity in printed parts
Can be age hardened to optimize strength and ductility
The combination of properties make GH3536 suitable for aerospace, power generation, oil & gas, and chemical processing components exposed to extreme temperatures and stresses. Both new part fabrication and repair of worn components can benefit from using this advanced powder.
GH3536 Alloy Powder Composition
GH3536 has a complex composition designed to provide an optimal balance of properties. The nominal composition is shown below:
| Element | Weight % |
| Nickel (Ni) | Balance |
| Chromium (Cr) | 13.5 – 16.0 |
| Cobalt (Co) | 12.0 – 15.0 |
| Tungsten (W) | 5.0 – 7.0 |
| Tantalum (Ta) | 3.0 – 5.0 |
| Aluminum (Al) | 2.8 – 3.8 |
| Titanium (Ti) | 0.5 – 1.5 |
| Niobium (Nb) | 0.5 – 1.5 |
| Hafnium (Hf) | 0.2 – 0.8 |
| Carbon (C) | 0.05 – 0.15 |
| Boron (B) | 0.01 – 0.03 |
