EN 10149-2 is the European Standard for hot-rolled flat products made of high yield strength thermo-mechanically rolled steels for cold forming. Steels encompassed by this specification have minimum yield strengths ranging from 315 MPa to 460 MPa for thicknesses ranging from 1.5 mm up to 20 mm.EN 10149-2 specification also covers steel grades having minimum yield strengths of 500 to 700 MPa in thicknesses of 1.5 to 16 mm.EN 10149-2 standard main steel grade:S650MC,S700MC,S600MC,S550MC,S500MC,S460MC and so on
