Our product portfolio also includes hot-rolled micro-alloyed steel. This is specified in detail in the DIN EN 10149-2 standard and the grades S315MC, S420MC, S500MC to S960MC are classified. Hot-rolled micro-alloyed steel is a central component of our product portfolio. This steel grade is a hot-formed, micro-alloyed steel that has specific properties due to its special composition and production. These are characterized in particular by excellent cold formability, high yield strength and – which is particularly relevant for industrial applications – excellent weldability.

Our range also includes specific hot-rolled micro-alloyed steel in accordance with DIN EN 10149-2. This standard specifies the technical delivery conditions for hot-rolled flat steel products for cold forming. This standard distinguishes between non-alloyed steels, micro-alloyed steels and low-alloyed steels.

DIN EN 10149-2 distinguishes and classifies various grades of hot-rolled micro-alloyed steel. Of these, we have grades S315MC to S960MC in our product portfolio. These steel grades differ in terms of their minimum yield strength and tensile strength. We therefore offer the right hot-rolled micro-alloyed steel for almost every requirement and every specific project. Our customers can therefore look forward to a diverse product selection that is tailored to their needs.

Hot-rolled micro-alloyed steels are low-alloyed and high-strength. They offer maximum strength with exceptional formability. The steels in the MC series are used for cold-formed components in a wide variety of designs. These grades are primarily used to manufacture the following parts.

Hot-rolled steel is usually supplied with a descaled or pickled and oiled surface. In this case, both sides are given a protective layer of oil that is chemically neutral, non-drying and free from foreign bodies. The oil layer can be removed with alkaline solutions or other common solvents. Alternatively, hot-rolled steel can also be supplied in the rolled condition, i.e. the surface has a thin, adherent layer of scale with varying coloration. Pores, slight scars, slight marks, slight scratches, discolorations and kinks from uncoiling are permissible. However, the surface quality must be free of overlaps, bubbles, peeling, cracks and scratches, as these can impair usability.
