Duplex stainless steel round bar offers a compelling blend of superior strength and excellent corrosion protection. This special combination arises from its makeup, containing both martensitic and ferrite phases. The presence of austenite improves ductility, while the magnetic phase contributes to increased strength. As a result, duplex steel round bars find application in environments where both structural integrity and resistance to pitting, crevice corrosion, and stress corrosion cracking are crucial - areas such as crude and gas pipelines, chemical processing plants, and desalination systems. Its superior properties often make it an economically viable alternative to more costly or less durable materials.
