| 1.6523 (DIN 17210 : 1986-09) | 21 NiCrMo 2 | 1.6523 | DIN 17210 : 1986-09 | DIN 17210 : 1986-09 replaced by DIN EN 10084 : 1998-06 | Replaced | Germany | 20NiCrMo2-2 | 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 degrees C, the best application up to 60 mm nominal size. |
