1) Remark: High-heat resistant nickel alloy in the form of solution-annealed seamless drawn tubes up to 50 mm and wall thicknesses up to 3 mm for aerospace hydraulic applications. The alloy is resistant to the effects of hot gases and combustion residues above 550°C and has excellent high-temperature strength and wear properties combined with good resistance to oxidation and carburization and can be used up to 1000°C (highest application temperature in air). For application temperatures above 600°C the delivery condition solution annealed should be selected. In the temperature range 600 to 800°C, the material tends to become brittle.
