EN 10025 S355 Steel. S355 steel is a European standard structural steel grade, according to EN 10025-2:2004, material S355 is divided into 4 main quality grades:S355JR (1.0045), S355J0 (1.0553), S355J2 (1.0577) and; S355K2 (1.0596). The properties of structural steel S355 is better than steel S235 and S275 in yield strength and tensile strength.
