Duplex steel coils are known for their unique two-phase microstructure, blending austenitic and ferritic grades. This composition gives them an outstanding strength-to-weight ratio and excellent toughness. They offer remarkable resistance to various forms of corrosion, including pitting and stress corrosion cracking, while also maintaining good weldability and formability for versatile fabrication needs.
