Material Description

Material Number	Material Number (single)	Standard	Range of Application	Standard Status	Country	Predecessor
2.4952 (DIN EN 10090 : 1998-03)	2.4952	DIN EN 10090 : 1998-03	Supersedes DIN 17480 : 1992-05	Valid	Germany	NiCr 20 TiAl	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.
