Corten Steel S355J2WP Plates
S355J2WP is a European standard atmospheric corrosion resistant steel, belongs to the weathering steel plate, is a kind of low alloy steel made by adding a certain amount of alloying elements in ordinary steel. Weathering steel atmospheric corrosion resistance can be 2-8 times of ordinary carbon steel, with high mechanical properties, welding properties, and the longer the time, the more obvious corrosion resistance.

S355J2WP corten metal sheet application range
S355J2WP is weathering steel, that is, atmospheric corrosion-resistant steel, is between ordinary steel and stainless steel series of low alloy steel, weathering steel from plain carbon steel to add a small amount of copper, nickel and other corrosion-resistant elements and become a high-quality steel with strong, ductile, molding, welding and cutting, abrasion, high temperature, fatigue resistance and other characteristics, weathering for the plain carbon steel, 2-8 times, painting for the plain carbon steel, 1.5 ~ 10 times. At the same time, it is rust-resistant, so that the components of corrosion resistance and life extension, thinning and consumption reduction, labor-saving and energy-saving features. Weathering-resistant steel is mainly used for steel structures that are exposed to the atmosphere for a long time, such as railroads, vehicles, bridges, pylons, photovoltaic, and high-speed projects. It is used in the manufacture of containers, railway vehicles, oil derricks, seaport buildings, oil extraction platforms and chemical and petroleum equipment containing hydrogen sulfide corrosive media such as containers and other structural components.
