1.6523 (DIN EN 10084 : 1998-06) 20NiCrMo2-2 1.6523 DIN EN 10084 : 1998-06 DIN EN 10084 : 1998-06 replaced by DIN EN 10084 : 2008-06 Replaced Germany 21 NiCrMo 2 20NiCrMo2-2 1.1.1 ≥ -60 1)
1) Remark: Steel 20NiCrMo2-2 is suitable for parts in vehicle manufacturing and machine engineering, which are wear loaded at mean core strength, high ductility and fatigue strength (e.g. gear wheels, shafts, axles). Lowest application temp. -60 °C, most favorable application area up to 60 mm nominal size.
