ASTM A588 Corten Steel
Our ASTM A588 Corten Steel precise control of alloying elements creates a protective oxide layer that actually improves over time. The copper-chromium matrix (Cu 0.20-0.40%, Cr 0.40-0.70%) develops a dense patina that resists flaking, while carefully controlled phosphorus content ensures excellent cold weather performance down to -34°C.
Available in plates (5-200mm), structural shapes, and custom profiles, this material demonstrates consistent mechanical properties across all product forms. The steel's enhanced atmospheric corrosion resistance makes it particularly valuable for transportation infrastructure and industrial structures where maintenance access is challenging.
