DIWETEN 355+M
DIWETEN 355+M introduction
DIWETEN 355+M is a fine grained structural steel with improved atmospheric corrosion resistance.
Due to its chemical composition, this material develops a patina with increased resistance against the
atmospheric corrosion in comparison with the normal structural steels.
DIWETEN 355+M has minimum yield strength of 355 MPa in its delivery condition ex works (referring
to the lowest thickness range). The thermomechanical rolling process allows using less alloying
elements, leading to a lower carbon equivalent and hence an improved weldability compared to
normalized weathering steels of the same strength.
