2.4952 (DIN EN 10302 : 2002-09) NiCr20TiAl 2.4952 DIN EN 10302 : 2002-09 DIN EN 10302 : 2002-09 replaced by DIN EN 10302 : 2008-06 Replaced Germany NiCr20TiAl 3.4 ≤ 1000 1)
1) Remark: The material NiCr20TiAl, material number 2.4952, is used for creep-strength-stressed construction components in belts, sheets, rods, wires and forgings. It is listed in the material specifications of the Deutsche Luftfahrt [German Aviation] WL 2.4631-1 : 1993-8, WL 2.4631-2 : 1993-08 sowie WL 2.4631-100 : 1993-08 with the material number 2.4631. NiCr20TiAl possesses a high creep strength up to temperatures of 850 degrees C and it has very good resistance to scaling. The nickel-chrome alloy can be hardened by adding aluminium and titanium. Its resistance to corrosion resembles that of NiCr20Ti. It is used for highly-stressed construction components, for example gas turbine shovels, discs, shafts, pre-combustion chambers in diesel motors, valves, hot work tools, sledge hammers, forging saddles, pressure tools, shearing blades, screws and nuts. Processing properties: formability: good (annealed) weldability: possible, but not customary
