What is S235J0W steel plate with enhanced atmospheric corrosion resistance

S235J0W steel plate is an improved weathering structural steel used for welding, bolting and riveting components. S235J0W steel has enhanced atmospheric corrosion resistance for applications at ambient temperature. In order to achieve anti-corrosion properties, some specific alloying elements, such as: P, Cu, Cr, Ni, Mo, etc. are added, so as to form a protective oxide layer on the metal surface under various climatic conditions. Implementation specification: EN10025-5, steel number: 1.8958.

The S235J0W steel grade consists of the following parts:
Symbol letter S: structural steel;
The yield strength value of the thickness less than 16mm: the minimum yield value;
J0 is the quality trademark for regular impact energy;
The letter W indicates that the steel has the ability to resist atmospheric corrosion;
FN: Boiling steel is not allowed;
FF: fully killed steel

S235J0W specification, shape, weight and tolerance: The specification, shape and allowable tolerance of the steel plate shall comply with the 2.2 rules in 2004 in EN10025-1.

S235J0W delivery: S235J0W steel plate is usually delivered in hot rolled, normalized condition or normalized rolled condition of the same condition. The S235J0W steel plate shall be delivered by shearing or flame cutting.
