Industry

Weldable fine grain structural steels are in compliance with the EN 10025-3:2004 standard, which defines four levels of mechanical properties. Each grade can be obtained with guaranteed impact properties at -20°C (N grades), or for low-temperature applications at -50°C (NL grades).

Weldable fine grain structural steels are either normalised or obtained by normalising co-lamination and thus keep their mechanical properties if the welded parts are normalised.

These steels are used for welded parts that have to withstand high levels of strain. Typical applications are bridges, pylons and other architectural structures.

Since 1 July 2013, the Construction Products Regulation (Regulation (EU) No. 305/2011 – CPR) has required that CE marking be affixed to all products delivered in accordance with a harmonised standard (e.g. EN 10025). This CE marking guarantees, for the uses defined in the standard, the properties described in the declaration of performance submitted by the manufacturer.

All of the steels in this data sheet comply with this Regulation.

The corresponding declarations of performance are available on our website at:

Options available (after prior agreement):

Reduced carbon equivalent value
Transversal impact test
Improved deformation properties perpendicular to the surface of the product as per EN 10164 (Z test)
Suitability for cold forming
Post-weld heat treatment test (PWHT)
Other options specified in the standard
