S355K2+N Characteristic

S355K2+N is a low carbon, high tensile strength structural steel which can be readily welded to other weldable steel.

With its low carbon equivalent, it possesses good cold-forming properties. The plate is produced by fully killed,

fine grain steel process and supplied in n normalized or controlled rolling condition.

S355K2+N Application

Structural application in freight cars, transmission towers, dump trucks, cranes, trailers, bull dozers, excavators,

forestry machines, railway wagons, dolphins, penstocks, pipes, highway bridges, building structures,

oil and gas platforms, offshore structures, shipbuilding, power plant, palm oil equipments and machineries,

fans, pumps, lifting equipments and port equipments.
