Katalor is a very famous supplier of atmospheric corrosion steel in China, we can produce all kinds of atmospheric corrosion resistant steel, providing high quality S355J0WP atmospheric corrosion steel.
S355J0WP steel is a kinds of atmospheric corrosion resistant steel which belong to EN10155 standard, It is a kind of low alloy steel made by adding a certain amount of alloying elements in the ordinary steel, the main components are Cu, P, Cr, Ni and other elements, Weathering steel's characterized is being able to resist corrosion under the natural atmospheric conditions.
Weathering steel is not stainless steel, at first it will be getting corrosion as same as ordinary steel, but later the condition is different. After rust a period of time, weathering steel's surface will enrichment with Cu. P and other trace elements, and it will formations a dense layer of amorphous state rust layer organization, and it will combination with the matrix in a very firm condition. In a certain extent this stable rust layer can against the atmosphere of water vapor and harmful ions intrusion, to prevent further corrosion of the metal.
S355J0WP resistant atmospheric corrosion steel is widely used in aerospace, electricity, petrochemical, shipbuilding, machinery, electronics, environmental protection and other industries.
