| 1) Remark: The material NiCr20Co18Ti with the material number 2.4969 is, as aviation material with the material number 2.4632, also contained in the Werkstoff-Leistungsblatt der Deutschen Luftfahrt editions WL 2.4632-1 : 1993-08, WL 2.4632-2 : 1993-08, WL 2.4632-3 : 1993-08, WL 2.4632-4 : 1993-08 and WL 2.4632-100 : 1993-08. It is a precipitation-hardening nickel-chromium-cobalt alloy with high creep strength depending on time at temperatures of up to approximately 900 °C. Besides, it possesses good resistance to corrosion and oxidation at high temperatures. Vanadin-pentoxide, sodium- und sulphur compounds can lead to hot-gas corrosion, though. Application for extremely stressed construction components, such as e.g. gas turbine blades, casing parts, afterburner parts, discs, shafts, tools for hot working, forging hammers, forging saddles, pressing tools, shear blades, springs.
