EN 10149-2 S550MC high yield strength steel
EN 10149-2 Grade S550MC steel is fine-grain steel with good cold formability, S550MC Specification for hot-rolled flat products made of high yield strength steels for cold forming. It is ideal for applications requiring low weight, high strength and good formability. Typical applications include telescopic booms, earthmoving equipment, agricultural machinery, truck and trailer frames. EN 10149-2 Classification The steel grades S315MC, S355MC, S420MC, S460MC, S500MC and S550MC of this European Standard are alloy quality steels and the steel grades S600MC, S650MC, S700MC, S900MC and S960MC of this European Standard are alloy special steels according to EN 10020.
