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.
S355 steel is a European standard structural steel, according to EN 10025-2, material S355 is mainly divided into 4 quality grades:
S355JR (1.0045)
S355J0 (1.0553)
S355J2 (1.0577)
S355K2 (1.0596)
The structural steel S355 is better than steel S235 and S275 in yield strength, tensile strength and other properties.
