S355NL - Structural Steel Plate

Associated Standard: BS EN 10025-3


S355NL is a hot rolled, medium tensile, low carbon manganese steel which is readily weldable and possess good impact resistance (also in sub-zero temperatures).

This material is commonly supplied in the untreated or normalized condition and is available in several variations (denoted by additional letters and/or digits) which offer slight modifications of chemical composition and mechanical properties.

Machinability of this material is similar to that of mild steel.
