WTSt 37-3 is the German standard SEW 087 under atmospheric corrosion resistant steel, also known as weathering steel. Is obtained by adding a certain amount of common steel alloying elements made ​​of a low alloy steel, the main component is divided into Cu, P, Cr, Ni and other elements, characterized by weathering steel to resist corrosion under natural atmospheric conditions.

Weathering steel is not stainless steel, initially as with ordinary steel will rust, the later the situation is different. After a period of weathering steel corrosion steel surface as Cu, P enrichment and other trace elements, form a dense rust layer amorphous tissue, and the substrate with a very strong, this layer of rust stabilized to a certain extent against the water vapor in the atmosphere and the intrusion of harmful ions and prevent further corrosion of the base metal.

WTSt 37-3 weathering steel characteristics and uses:
WTSt 37-3 weathering steel with high toughness steel, plastic casting, forming, welding and cutting, abrasion, high temperature, anti-fatigue and other characteristics; weathering is 2 to 8 times the carbon steel, carbon steel coating properties of the 1.5 to 10 times. Meanwhile, it has a rust-resistant, corrosion-resistant components to make life extension, thinning saving, labor saving features. Weathering steel is mainly used for railway vehicles, bridges, towers and other long-term exposure of the steel used in the atmosphere. For the manufacture of containers, railway vehicles, oil derricks, harbor construction, oil platforms and chemical petroleum equipment containing hydrogen sulfide corrosion medium container and other structural parts.
