Super Duplex Steel Fasteners find extensive application in high-strength and corrosion-resistant industries. Some common applications are offshore oil and gas platforms, subsea pipelines, chemical processing facilities, and marine engineering. High-pressure, high-temperature equipment like pressure vessels, heat exchangers, and storage tanks are suitable for such fasteners. Their higher resistance to chloride stress corrosion cracking, pitting, and crevice corrosion makes them ideal for challenging conditions in petrochemical, desalination, power generation, and other severe industrial applications.
