Corten steel sheet

What is corten steel plate?

Corten-A corrosion-resistant steel plate (corrosion-tensile steel) is the abbreviation of atmospheric-corrosion-resistant, high-strength steel. Corten-A, weathering steel, is made by adding a little copper, chromium, phosphorus, and other elements to ordinary steel, and is made by special treatment. Its weathering and corrosion resistance is three to eight times higher than ordinary steel. According to different types and uses, Corten-A can be divided into four types: COR-TEN A, COR-TEN B, COR-TEN C, COR-TEN B-QT. Among them, the weather resistance and corrosion resistance of COR-TEN A is five to eight times better than that of ordinary steel, while COR-TEN B is four times better.

Comparison of Corten steel sheet implementation standards at home and abroad.

China: GB/T 4171-2008 Standard Specification for the Implementation of Weathering Structural Steel Plates.

American Standard: ASTM A606-04 High-strength low-alloy hot-rolled and cold-rolled steel plates and strips resistant to atmospheric corrosion.

ASTM A871/A871M-03 Atmospheric corrosion resistant high-strength low-alloy steel plate.
Japanese standard: JIS G 3114:2004 Standard Specification for Hot Rolled Atmospheric Corrosion Resistant Structural Steel.

Main applications of Corten steel sheet

It is widely used in the production of train carriages, containers and bridges. Weathering steel is used as a building facade material, and has a certain history in North America, Western Europe, Australia and Asia, Japan and South Korea. The earliest example is the Chicago Civic Center Building built in 1965. Weather-resistant steel can be used as a facade material. Compared with ordinary steel, weather-resistant steel has superior corrosion resistance.
