1.0980 (DIN EN 10149-2 : 1995-11) 1.0980 DIN EN 10149-2 : 1995-11 DIN EN 10149-2 : 1995-11 replaced by DIN EN 10149-2 : 2013-12 Replaced Germany S420MC ≥ -20 1.1 1)
1) Remark: The thermomechanical rolled steel S420MC, mat. no. 1.0980, is used for cold formed components like vehicle frames, axles and special sections. Tempering > 580 deg. leads to an decrease of the strength of the thermomechanical treated material. The lowest application temperature amounts to - 20 deg. At this temperature the proof of the notch impact energy of min. 40 J can be agreed. The min. bending mandrel diameter for the 180°-bending test (transversal specimen) amounts to 0.5*t (t=specimen thickness).
