355MC Thermo-Mechanically Hot Rolled Plate

 355MC Thermo- Mechanically Hot Rolled Plate Prodcts

EN 10149-2: Chemical & delivery conditions, EN 10051 (table 4): Tolerance information
S355MC is a Thermo-Mechanically rolled fine grained hot rolled weldable material suitable for cold forming. S355MC – S: Structural Steels, 355: Minimum Yield Strength, M: Longitudinal Charpy V-notch impacts, temperature not lower than -20 degrees C.
This material has a very clean smooth surface finish for laser cutting; it can bend not giving up tension during processing, this could happen when using S355JR. S355MC material is not suited for areas with high continual heat; it will start losing its mechanical properties. In these applications S355JR is best used without losing mechanical properties. S355MC will have excellent formability in the cold form, weld ability and impact strength.
S355JR is not a replacement for S355MC; there are differences between the two callouts. S355JR is according to EN 10025 which receives mechanical figures with the elements in the steel, S355MC is a fine grain steel according to EN 10149 which receives its mechanical figures over a strong cooling after rolling (shock cooling). Material is would be better than to ASTM A572 Gr. 50; this is the closest American grade.
S355Mc will conform to EN 10149-2, delivery conditions and chemical information. EN 10051 will supply the tolerance, use table 4 – based on the plate width this will give you tolerance information.
Typical Applications:
Truck chassis assemblies
Automotive industry        
Earth moving machines
Farm machinery
In these applications this high strength steel saves on weight and increases payload.
