COR-TEN has served as weathering steel (atmospheric corrosion- resistant steel). 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. (2015 end)
