1. S355J0W, S355K2W, S355J0WP material performance introduction:
S355J0W, S355K2W, S355J0WP comply with European standard EN10025-5:2004. S355J0W, S355K2W, S355J0WP are one of the weather-resistant steel plates produced by Wugang, namely atmospheric corrosion-resistant steel, which is a low-alloy steel series between ordinary steel and stainless steel. Weather-resistant steel is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel. It has the characteristics of high-quality steel such as toughness, plastic extension, forming, welding, abrasion, high temperature, and fatigue resistance; weather resistance is 2 to 8 times that of ordinary carbon steel, and paintability is 1.5 to 10 times that of ordinary carbon steel. At the same time, it is rust-resistant, makes components corrosion-resistant and prolongs life, reduces thinning and reduces consumption, and saves labor and energy. Weathering steel is mainly used for steel structures such as railways, vehicles, bridges, towers, etc. that are exposed to the atmosphere for a long time. It is used to manufacture containers, railway vehicles, oil derricks, port buildings, oil production platforms, and chemical and petroleum equipment containing hydrogen sulfide corrosive media and other structural parts.
