Steel S355MC – Material 1.0976
S355MC steel (material 1.0976) is a thermomechanically rolled steel with a high yield strength. It is essentially a type of subdivision of S355 steel. S355MC has a minimum yield strength of 355MPa and a tensile strength of 430-550 MPa.
Meaning/Designation
S355MC meaning: S for structural steel, 355 indicates the minimum yield strength in MPa, M is for thermomechanically rolled, C is for cold forming. (For more European steel name meanings/designations)
