What is the corten steel and its application?

Cortent steel, that is, atmoSPHEric corrosion-resistant steel, is a series of low-alloy steels between ordinary steel and stainless steel. Corten steel is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel. Properties such as drawing, forming, welding, abrasion, high temperature, fatigue resistance, etc .; weather resistance is 2 to 8 times that of ordinary carbon steel, and paintability is 1.5 to 10 times that of ordinary carbon steel. At the same time, it has the characteristics of rust resistance, anti-corrosion and life extension, thinning and consumption reduction, labor saving and energy saving. Corten steel plate and sheet is mainly used for steel structures such as railways, vehicles, bridges, and towers that have been exposed to the atmosphere for a long time. Corten steel plate is used to manufacture structural parts such as containers, railway vehicles, petroleum derricks, seaport buildings, oil platforms and containers containing hydrogen sulfide corrosive media in chemical petroleum equipment.

Corten steel properties

It is characterized in that the alloy composition and weight percentage content of weathering steel are: C: 0.12 to 0.21, Si: 0.2 to 2.0, Mn: 0.7 to 2.0, S ≤ 0.036, P ≤ 0.034, Cu: 0.10 to 0.40, Al <0.2 The rest are Fe and trace impurities. Through alloying of Cu, Mn, Si, Al, etc., and simple adjustment of some element content of ordinary low carbon steel (Q235 steel), it can produce good atmospheric corrosion resistance without changing the production process conditions of Q235 steel Economical weathering steel with comprehensive mechanical properties.
 
Corten steel(that is, atmospheric corrosion-resistant steel) is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of toughness, plastic extension, forming, welding, abrasion, high temperature, fatigue and other characteristics of high-quality steel. The weather resistance is 2 ~ 8 times, the coating is 1.5-10 times that of ordinary carbon steel, which can be used thinner, bare or simplified. The steel has the characteristics of rust resistance, corrosion resistance and life extension, thinning and consumption reduction, labor saving and energy saving, and benefits component manufacturers and users. Corten steel products are used to manufacture structural parts such as containers, railway vehicles, petroleum derricks, seaport buildings, oil platforms and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.
