Corten Steel Q235NH

Weathering resistant steel, also known as atmospheric corrosion resistant steel, is a steel containing specific alloying elements that make it have high corrosion resistance when exposed to atmosphere, water and other corrosive media. Among them, Corten Steel Q235NH is the full name of atmospheric corrosion resistant hot continuous rolled steel, also known as Cowden steel, corrosion resistant steel, widely used in: Containers, power plant chimneys, railway engineering and other outdoor steel such as large outdoor sculpture steel, weathering steel (that is, atmospheric corrosion resistant steel) is between ordinary steel and stainless steel series of cheap and high-quality low alloy steel series, in the integration of modern metallurgy new mechanisms, new technologies and new processes after sustainable development and innovation, is one of the world's super steel technology frontier level of steel series.

The weatherability of weathering steel mainly depends on its composition, heat treatment process and surface state. Through appropriate alloying element ratio and heat treatment process, a small amount of corrosion resistant elements such as copper, chromium, phosphorus, nickel, molybdenum, niobium, vanadium and titanium are added on the basis of ordinary carbon steel to form a protective layer on the surface of the metal substrate to improve atmospheric corrosion resistance and extend its service life. Weathering steel because of its strong, plastic extension, molding, welding and cutting, abrasion, high temperature, corrosion resistance and other characteristics are used in the production of railway vehicles, containers, environmental protection equipment, towers, etc., in recent years, more and more used in the landscape decoration industry, such as rust sculpture, landscape curtain wall, retaining wall and so on.
