1. Introduction to S355J2W steel plate S355J2W is a European standard atmospheric corrosion-resistant steel. It is a weather-resistant steel plate. It is a low-alloy steel made by adding a certain amount of alloy elements to ordinary steel. The atmospheric corrosion resistance of weathering steel is 2-8 times that of ordinary carbon steel. It has good mechanical properties, welding properties, etc., and the longer the time, the more obvious the corrosion resistance effect.
2. S355J0W, S355J2W, S355K2W steel plate implementation standards: implement EN10025-5:2004 standard.
3. Delivery status of S355J0W, S355J2W, S355K2W steel plates: delivered in hot rolled, normalized or normalized rolling state.
4. Application scope of S355J0W, S355J2W, S355K2W steel plates: S355J0W, S355J2W, S355K2W are weather-resistant steel, which is atmospheric corrosion-resistant steel. It 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 copper, nickel and other corrosion-resistant elements added. It has high quality Steel has the characteristics of strength, plastic extension, forming, welding and cutting, abrasion, high temperature, and fatigue resistance; its weather resistance is 2 to 8 times that of ordinary carbon steel, and its paintability is 1.5 to 10 times that of ordinary carbon steel. At the same time, it is rust-resistant, can resist corrosion and extend the life of components, can reduce thickness and reduce consumption, save labor and energy, etc. Weathering steel is mainly used in steel structures that are exposed to the atmosphere for a long time, such as railways, vehicles, bridges, towers, photovoltaics, and high-speed projects. It is used to manufacture structural parts such as containers, railway vehicles, oil derricks, harbor buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.
