S420MC是EN10149-2:1996标准中的一种热轧冷变型用高屈服温度钢
它的化学成分如下：

Material Name:S420MC
" J$ f6 P4 F9 |3 W2 s* s3 G' SStandard DIN EN 10149-2 : 1995-11
Material Group: Hot rolled flat products made from high yield strength steels (EN)

Material Description: The thermomechanical rolled steel S420MC,  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).
