S355J2 is a low carbon manganese, high tensile strength structural steel that belongs to the European standard EN 10025-2.
Some typical material applications include bridges, pressure vessels, offshore structures, wind turbines, mining equipment, and cranes.
- Good corrosion resistance
- High strength and durability
- Superior weldability
S355J2 steel has moderate corrosion resistance in atmospheric conditions, making it suitable for outdoor structures. However, it is not recommended for direct exposure to seawater or other highly corrosive environments. S355J2 steel contains small amounts of alloying elements, such as manganese, silicon, and carbon, which enhance its mechanical properties but do not significantly improve its corrosion resistance.
Therefore, if the steel is used in environments prone to corrosion, appropriate measures, such as protective coatings or cathodic protection, must be taken to prevent or reduce corrosion.
