2.4951 (DIN 17742 : 2002-09) 2.4951 DIN 17742 : 2002-09 DIN 17742 : 2002-09 replaced by DIN 17742 : 2020-12 Replaced Germany NiCr20Ti 3.4 1)
1) Remark: The material NiCr20Ti with the material number 2.4951 is, as aviation material with the material number 2.4630, also contained in the Werkstoff-Leistungsblatt der Deutschen Luftfahrt editions WL 2.4630-1 : 1993-08, WL 2.4630-2 : 1993-08, WL 2.4630-3 : 1993-08, WL 2.4630-4 : 1993-08 and WL 2.4630-100 : 1993-08. It is scale-resistant up to approximately 1100 °C and possesses high corrosion-resistance and creep strength depending on time up to 750 °C as well as good resistance to temperature variations. The application in carbonizing or sulphur-bearing furnace atmospheres is not recommendable at higher temperatures. Application for construction components in gas turbines (rings, casing parts), parts for the construction of industrial furnaces, pallets and baskets for the heat treatment of construction components as well as for components in aviation and space travel. Processing properties: Formability: good Weldability: good (Werkstoff-Leistungsblatt der Deutschen Luftfahrt/WL: material specification of the German aviation)
