Material Description

Material Number Material Number (single) Standard Scope Standard Status Country Successor Application temperature [°C] VDA 231-106 classification
1.7149 (DIN 1652-3 : 1990-11) 1.7149 DIN 1652-3 : 1990-11 DIN 1652-3 : 1990-11 replaced by DIN EN 10277-4 : 1999-10 Replaced Germany 20MnCrS5 ≥ -25 1.1 1)
1) Remark: The steel 20 MnCrS 5 in opposite to 20 MnCr 5 is used for larger parts with higher core strength and better machinability in the vehicle and mechanical engineering (e.g. gearboxes, joint parts, gears, bolts). The lowest application amounts to -25 °C, the best application up to 80 mm nominal size.
