-S355J2 is a kind of low alloy high-strength structural steel, which belongs to the European standard hot rolled structural steel, and the executive standard is EN10025. It has high strength, good weldability, formability and corrosion resistance, and is widely used in the fields of construction, bridge, machinery, ship, marine engineering and so on.
-S355J2G3 is a common non-alloyed structural steel widely used in building and engineering structures, especially for welding and steel fabrication. Its high strength and good toughness make it very popular in bridges, building frames, heavy machinery, ships and other structural engineering.
