S550MC

S550MC is a high yield steel under the EN10149: Part2 specification. It is a structural hot rolled steel material with high yield strength and excellent cold forming characteristics.
S550MC can be used in numerous applications including steel framed structures, structural pipes and cold rolled sections. As the material is designed to be used in load bearing applications, care should be taken when ordering to ensure that the steel has qualities required for the job in hand.
Heat treatment of S550MC is not advisable as this will reduce the yield strength of the material.
