COR-TEN steel is a highly practical type of steel widely used all over the world. COR-TEN steels—also known as (weathering steels, corrosion-resistant steels), rusted steels, aged steels, or PATINAX—are steels that exhibit higher corrosion resistance compared to mild steels and low-carbon steels. These steels are classified under ASTM specifications as A242 and A588. COR-TEN steels, which demonstrate mechanical properties up to 30% higher than conventional steels, allow reduced steel weight in structural applications due to thinner sections. After approximately 6 months of exposure to the atmosphere, an aesthetically pleasing, warm dark-brown, rust-like layer forms on the surface. Since this layer prevents corrosion from continuing on the metal surface, COR-TEN steels do not require painting or expensive anti-corrosion maintenance. However, if they are painted, the protective life of the paint is longer compared to paint applications on ordinary steels. Any defects formed during the painting process are compensated by COR-TEN’s corrosion-inhibiting properties, extending paint life and providing economic advantages.
COR-TEN steels, with their high resistance to atmospheric corrosion, eliminate the need for protective coatings such as paint and varnish, making them an environmentally friendly and long-lasting product. They also feature high yield strength (yield strength 355–960 MPa), which is one of the reasons they are frequently preferred in the petrochemical industry. COR-TEN materials can be welded using all welding methods. In addition, thin-gauge materials can be welded using spot welding.
The areas of use of COR-TEN steels are quite extensive. Frequently preferred applications include; bridges, water pipelines, exterior façade applications in buildings, agricultural machinery, railway wagons, oil wells, port constructions, petrochemical equipment, containers, chimneys, as well as outdoor artistic installations, landscaping projects, decorative garden accessories, interior and exterior decorative purposes, and architectural projects.
