A588 Weathering
A606/A588 (CORTEN/COR-TEN/Corten) Steel Product Guide
Applications | Specifications | Mechanical and Chemical Data | Tolerances
Overview
Also called COR-TEN/CORTEN/Corten, this is a unique steel alloy. When exposed to the outdoor environment, this material quickly develops an orange-brown rust-colored sheen that actually protects the material underneath it. Additionally, A588 steel exhibits high strength but is 20-30% lighter than comparable alloy steels. It is weldable, formable, and easily machinable. It is frequently used in industrial applications, freight cars, and decorative applications.
COR-TEN is a trademark of U.S. Steel Corp.
