Material Description

Material Number Material Name Material Number (single) Standard Standard Status Country VDA 231-106 classification
2.4982 (Stahl-Eisen-Liste : 1999) NiCr20CoMo 2.4982 Stahl-Eisen-Liste : 1999 Replaced Germany 3.4 1)
1) Remark: The material NiCr20CoMo with the material number 2.4982 is applied for parts of engines and gas turbines, like blades, discs, afterburner fans, springs as well as for tools for hot working. In air, it possesses a scale-resistance up to approximately 1000 °C. The welding (tungsten inert-gas method, resistance method) is only possible in the solution-annealed condition (subsequently solution-anneal again and artificial-age).
