Material Description: The thermomechanical rolled steel S420MC, is used for cold formed components like vehicle frames, axles and special sections.
8 w4 o/ k4 D; \' o- ^% H: {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. e- x. M( W! m
The min. bending mandrel diameter for the 180°-bending test (transversal specimen) amounts to 0.5*t (t=specimen thickness). |
