S355NL Steel Plates

S355N and S355NL used in the Passerelle Simone-de-Beauvoir in Paris

S355NL is a normalised weldable fine grain structural steel to EN10025-3. We have large stocks of S355NL with plates thicknesses from 6 mm to 200 mm available.

Plate widths are from 2 metres wide to 3m and up to 12m long

S355NL steel has a yield strength of 355 MPa at 16 mm at room temperature falling to 275 MPa at 250 mm. Its normalised.

The S355NL plates are all from Dillinger – so German steel – and typically have EN10204 3.2 MTC. S355N/NL comes in a normalised and a normalised with low temperature options.

We deliver normalised S355 plates to all major Asian ports on a CIF basis using conventional or container vessels depending on the widths of the plates ordered.

For customers in Europe S355NL plate can be ordered direct from Dillinger or from stock from AncoferWaldram. The EN 10025-3 standard can be purchased from the BSI
