What are the application and characteristics of S355J0WP weathering steel plate?

S355J0WP weathering steel plate is used for bridges, ships, power plant equipment, lifting and transportation machinery, machinery manufacturing and other engineering and welding structures with high load.

S355J0WP weathering steel plate belongs to weathering steel, i.e. atmospheric corrosion-resistant steel, which is a series of low-alloy steel between ordinary steel and stainless steel. Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel, such as strength, ductility, forming, welding and cutting, abrasion, high temperature and fatigue resistance;

The weathering resistance of S355J0WP weathering steel plate is 2-8 times of that of plain carbon steel, and the coating resistance is 1.5-10 times of that of plain carbon steel. At the same time, it has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving.

Weathering steel is mainly used in railway, vehicle, bridge, tower and other steel structures exposed to the atmosphere for a long time. It is used to manufacture containers, railway vehicles, oil derricks, seaport buildings, oil production platforms and containers containing hydrogen sulfide corrosive medium in chemical and petroleum equipment.
