DI-MC 355 B (EN S355M)
DI-MC 355 B (EN S355M) introduction
DI-MC 355 is a thermomechanically rolled, fine grained structural steel with minimum yield strength of
355 MPa in its delivery condition ex works (referring to the lowest thickness range). It fulfils the requirements
of EN 10025-4.
Due to its chemical composition, this material has a low carbon equivalent and hence excellent weldability. The
steel is preferentially used by the customers in constructional steelwork, hydraulic steelwork and mechanical
engineering, where exacting demands are placed on weldability.
Equivalent material: EN S355M
