Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country Predecessor VDA 231-106 classification
2.4952 (DIN EN 10090 : 1998-03) NiCr20TiAl 2.4952 DIN EN 10090 : 1998-03 Supersedes DIN 17480 : 1992-05 Valid Germany NiCr 20 TiAl 1.1.2 1)
1) Remark: NiCr20TiAl is a nickel-base alloy with high creep strength and very good scaling resistance. This alloy shows good corrosion resistance in exhaust condensate and good resistance to lead compounds at increased temperatures. Use: exhaust valves, valves, gas-turbine blades, discs and shafts.
