  • Product Detail

What is weathering steel?

Weathering steel, that is, atmospheric corrosion-resistant steel, is a low alloy steel series between ordinary steel and stainless steel, weathering steel from ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements, with high-quality steel, strong, plastic extension, forming, welding, abrasion, high temperature, fatigue resistance and other characteristics; weather resistance for ordinary carbon steel 2 ~ 8 times, coating for ordinary carbon steel 1.5 ~ 10 times. At the same time, it has the characteristics of rust resistance, so that the components of corrosion resistance to extend life, thinning and reducing consumption, saving energy and other characteristics. Weathering steel is mainly used for steel structures used in railways, vehicles, bridges, towers, photovoltaic, high-speed engineering, etc., which are exposed to the atmosphere for a long time. Used in the manufacture of containers, railway vehicles, oil derricks, harbor buildings, oil recovery platforms and chemical and petroleum equipment containing hydrogen sulfide corrosive media containers and other structural components

Principle of weather-resistant steel

The addition of phosphorus, copper, chromium, nickel and other trace elements to the steel surface to form a dense and strong adhesion of the protective film to prevent the spread and development of rust in the rust layer to protect the substrate below the rust layer to slow down its corrosion rate. In the rust layer and the substrate formed between about 50μm ~ 100μm thick amorphous spinel-type oxide layer dense and good adhesion with the base metal, due to the existence of this layer of dense oxide film, prevented the atmospheric oxygen and water to the steel substrate penetration, slowed the corrosion to the steel material deep development, greatly improving the ability of steel materials to resist atmospheric corrosion. Weathering steel can be used thin, bare or simplified coating, and make the products corrosion-resistant life extension, labor saving, upgrading the steel system, but also a modern metallurgy can be integrated into the new mechanism, new technology, new technology and make its continuous development and innovation of the steel system.
