Description

The highly creep-resistant aviation material NiCr20TiAl with the material number 2.4631 is contained in the Werkstoff-Leistungsblatt der Deutschen Luftfahrt editions WL 2.4631-1 : 1993-08, WL 2.4631-2 : 1993-08 and WL 2.4631-100 : 1993-08. DIN 17742 among other things contains the material NiCr20TiAl with the material number 2.4952. The material is hardenable, highly creep-resistant and scale-resistant up to about 1000 °C. NiCr20TiAl is corrosion-resistant, yet vanadin-pentoxide, sodium- und sulphur compounds can lead to hot-gas corrosion. Application for gas turbine blades, gas turbine rings and discs as well as for screws for operating temperatures up to about 815 °C. Processing properties: Formability: good (annealed) Weldability: possible, but not common (Werkstoff-Leistungsblatt der Deutschen Luftfahrt/WL: material specification of the German aviation)
