EN 10149-2 High strength low alloy steels
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.

High strength low alloy steels combine excellent mechanical properties, such as durability, fatigue resistance and impact resistance, with good formability and weldability. They are an excellent choice where weight reduction is a priority. Because of their high yield strength, they are frequently used as an alternative to structural steels.
