Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country VDA 231-106 classification Application temperature [°C]
2.4955 (DIN 17480 : 1992-05) NiFe25Cr20NbTi 2.4955 DIN 17480 : 1992-05 DIN 17480 : 1992-05 replaced by DIN EN 10090 : 1998-03 Replaced Germany 3.4 ≤ 700 1)
1) Remark: The material NiFe25Cr20NbTi with the material number 2.4955 is applied for, among other things, inlet and outlet valve cones for reciprocating-piston combustion engines. Under the influence of combustion gases, too, the material possesses a good resistance to heat and to temperature variations, a good corrosion-resistance, high alternating stress fatigue strength as well as good resistance to shocks and to wear. Application also for screws and nuts that, in uninterrupted continuous operation up to a temperature of approximately 700 °C, show good mechanical properties, high creep limits as well as high values for the creep tensile strength.
