| 1.7220 (DIN EN 10083-3 : 2007-01) | 34CrMo4 | 1.7220 | DIN EN 10083-3 : 2007-01 | DIN EN 10083-3 : 2007-01 replaced by DIN EN ISO 683-2 : 2018-09 | Replaced | Germany | 34CrMo4 | 34CrMo4 | 1.1.1 | 1) |
| 1) Remark: Steel 34CrMo4 is suitable for parts with high strength and toughness requirements at mean and higher heat-treatment sections (also large forged parts) in vehicle manufacturing, engine and machine engineering (e.g. shafts, gear wheels, steering knuckles). The steel shows high resistivity to static and dynamic loading. |
