Duplex steel bars find extensive use in challenging conditions thanks to their superior strength and resistance to corrosion. They are frequently used in construction to reinforce concrete structures, in maritime applications for building ships, and in industrial contexts for producing equipment and machinery. Because they resist stress corrosion cracking, they are well suited for chemical processing facilities and the oil and gas sectors. Furthermore, they serve in structural parts subjected to severe conditions, guaranteeing durability and long service life.
