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.
