The steel grade of the S550mc steel plate/sheet used for cold-formed components of the most varied designs. Their fields of application include the manufacture of:Longitudinal beams Frames Cold-pressed parts Cold-rolled sections Structural pipes.
The low-perlite steel grades offer excellent bending, flanging, cold-bordering and folding properties in both longitudinal and transverse direction. The bending radii specified below should be observed as minimum values.
