Atomfair GH3230 Nickel-Based Superalloy Powder
GH3230 is a Ni-based solid solution-strengthened superalloy, operating within 700–1050°C. It delivers high strength, excellent thermal fatigue resistance, stable microstructure, and outstanding resistance to heat corrosion and oxidation. Ideal for high-temperature structural components like aero-engine combustion chambers, compatible with the SLM process.
