| 1) Remark: NiCr20TiAl as a aviation material, material number 2.4631, is contained in `Werkstoff-Leistungsblättern der Deutschen Luftfahrt WL` (material data sheets) 2.4631, part 1 and 2 as well as part 100, issues 08.93. This material shows high creep strength up to 850 °C and very good scaling resistance. The nickel-chromium-alloy is hardenable due to the addition of aluminium and titanium. Its corrosion resistance is similar to NiCr20Ti. Application for maximum loaded components, such as gas turbine blades, discs, shafts, pre-combustion chambers in diesel engines, valves, hot working tools, sledge hammer, die blocks, pressing tools, shearing blades, screws and nuts. Processing properties: formability: well (annealed) weldability: possible, but unusual |
