S355 Grade Steel

S355 GradesS355 is a non-alloy European standard (EN 10025-2) structural steel.
S355 grade steel is a medium tensile, low carbon manganese steel which is readily weldable and possesses good impact resistance (also in sub-zero temperatures).

This material is commonly supplied in the untreated or normalised 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.
