Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country VDA 231-106 classification Application temperature [°C]
1.6523 (DIN 1652-3 : 1990-11) 21 NiCrMo 2 1.6523 DIN 1652-3 : 1990-11 DIN 1652-3 : 1990-11 replaced by DIN EN 10277-4 : 1999-10 Replaced Germany 1.1.1 ≥ -60 1)
1) Remark: The steel 21 NiCrMo 2 respectively 23 NiCrMo 2 is used for wear loaded parts in the vehicle and mechanical engineering with medium core strength, high toughness and high fatigue strength (e.g. gears, shafts, axles). The lowest application amounts to -60 °C, the best application up to 60 mm nominal size.
