cortenA is a type of Corten steel. Corten steel, also known as Corten steel, is divided into two categories: Corten A, CortenB, is the representative of the United States Cu-P series steel, belongs to the low alloy high-strength atmospheric corrosion-resistant structural steel, domestic called weathering steel.
Weathering steel, that is, atmospheric corrosion-resistant steel, is between ordinary steel and stainless steel series of low alloy steel, weathering steel from plain carbon steel to add a small amount of copper, nickel and other corrosion-resistant elements and become a high-quality steel with strong, plastic extension, molding, welding and cutting, abrasion, high temperature, fatigue and other characteristics; weathering for the plain carbon steel, 2-8 times, painting for the plain carbon steel, 1.5 ~ 10 times.
At the same time, it is rust-resistant, so that the components of corrosion resistance and life extension, thinning and consumption reduction, labor-saving and energy-saving features. Weathering-resistant steel is mainly used for steel structures that are exposed to the atmosphere for a long time, such as railroads, vehicles, bridges and pylons. It is used in the manufacture of containers, railway vehicles, oil derricks, seaport buildings, oil extraction platforms and chemical and petroleum equipment containing hydrogen sulfide corrosive media such as containers and other structural components.
