Product Description

Industrial A242 weathering steel SPA-H hot rolled corten steel plate

Weathering steel (corten steel), also known as atmospheric corrosion- resistant steel. It is a low alloy steel between ordinary steel and stainless steel. It is composed of ordinary steel with adding a certain amount of cooper and the corrosion resistant elements such as Cr, Ni, Ti and V. It has the characteristics of easy extension, high strength and fatigue resistance of ordinary steel, and it can reach 2-8 times of ordinary carbon steel in anti-corrosion. Corten steel plate has successfully overcome rust, steel's most weakest. When exposed to the atmosphere without painting, corten steel begins to rust in the same way as ordinary steel. BUT soon the alloying elements in COR-TEN cause a protective surface layer of the fine-textured rust to form, thereby suppressing corrosion rate. Since its development in 1993, the COR-TEN has been used in every field where steel applied, such as bridges, railway vehicle and buildings. At present, COR-TEN are attracting attention as being suited for resources and environmental concerns as well as reducing life-cycle costs.

Features of COR-TEN

Weathering Resistance

Thanks to high weather resistance, corten steel can be used without painting. Unpainted applications are not only offer the economic advantage of reducing repainting costs; they also offer aesthetic benefits associated with the calming color of the protective rust.

Paint Durability

COR-TEN is paintable in the same way as ordinary steel. In addition, even if a painting defect should occur, COR-TEN suppresses the progress of rust area and prolongs the services life of paint, thereby reducing repainting costs.

Weldability

While trace amounts of alloying elements such as copper (Cu) and chromate (Cr) are added to COR-TEN to ensure high weather resistance, the carbon content is lowered to provide appropriate weldability. Accordingly, COR-TEN can be welded using either manual, gas-shield or submerged arc welding.

Workability

COR-TEN possesses workability similar to ordinary steels of same strength.

Reliability

Since 1959 when COR-TEN began to be marked, more than 4.8 million tons of this material have been produced
