    Product Details(Feature/Advantages)

    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.
