DIWETEN 355+N
DIWETEN 355+N introduction
DIWETEN 355+N 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 non-alloyed structural steels.
DIWETEN 355+N has a minimum yield strength of 355 MPa in its delivery condition ex works
(referring to the lowest thickness range). Due to its restricted chemical composition, DIWETEN 355+N has a better weldability compared to respective steels produced according to
EN 10025-5.
