According to the guarantee conditions of delivery, China and some countries divide the ordinary carbon steel into three categories: Class A steel, which only guarantees the mechanical properties, not the chemical compositions； Class B steel, which only guarantees the chemical compositions, not the mechanical properties; special steel (Class C steel), which not only guarantees the chemical compositions, but also the mechanical properties. Class C steel Q355GNH cold rolled weathering steel angles is often used to manufacture important structural parts. Density of ordinary carbon steel: 7.85 g / cm3.

S500MC steel plate/sheet,EN10149 S500MC steel plate/sheet, under EN standard, we can regard S500MC steel plate/sheet as high yield strength steels for cold-forming steels.
