1.7147 (DIN EN 10084 : 1998-06) 1.7147 DIN EN 10084 : 1998-06 DIN EN 10084 : 1998-06 replaced by DIN EN 10084 : 2008-06 Replaced Germany 20 MnCr 5 20MnCr5 ≥ -25 1)
1) Remark: Steel 20MnCr5 is compared to 16MnCr5 suitable for higher dimension parts of higher core strength and favorable ductility qualities in vehicle manufacturing and machine engineering (gears, joint parts, gear wheels, bolts). Lowest application temp. -25 °C, most favorable range of application up to 80 mm nominal size.
