GH3536 offers excellent resistance to oxidation and corrosion, preventing material degradation in aggressive environments, such as those found in turbine systems and combustion chambers.
• Creep Resistance: Creep, the slow deformation of a material under constant stress, is a concern for components that must endure prolonged periods of exposure to high temperatures. GH3536’s excellent creep resistance ensures that components such as turbine blades and discs maintain their shape and mechanical properties, even after long-term exposure to high temperatures.
• Thermal Fatigue Resistance: In gas turbines and aerospace engines, components are subject to frequent temperature fluctuations due to rapid heating and cooling cycles. GH3536’s resistance to thermal fatigue ensures that components like turbine blades and combustion chambers can withstand these changes without cracking or losing structural integrity.
• High-Temperature Fatigue Strength: Components that are subjected to high mechanical stresses, such as turbine blades and nozzles, need to resist high-temperature fatigue. GH3536’s high-temperature fatigue strength allows these components to endure continuous operation without suffering from premature failure due to repeated stress cycles.
