Super Duplex Steel nuts are produced from a balanced blend of austenitic and ferritic stainless steels, providing an outstanding combination of corrosion resistance and mechanical strength. These nuts have very high tensile strength, superior hardness, and excellent fatigue properties. They act reliably at high temperature and withstand pitting, crevice corrosion, and stress corrosion cracking, especially in environments high in chloride. Their better strength-to-weight ratio renders them lighter in weight compared to standard stainless steel nuts without sacrificing high mechanical performance. They are apt for high-pressure, high-stress, and aggressive industrial conditions.
Super Duplex Steel nuts are extensively applied in quality demanding industries that need strength, durability, and resistance to corrosion. They have withstood aggressive chemicals and high pressure in chemical processing. In naval applications, they also resist seawater corrosion and provide long service life. In the oil and gas sector, these nuts have made fastening securely under harsh stress. These are also used in power generation and construction works where harsh conditions require high-performance fasteners. Their strength, corrosion resistance, and durability in combination guarantee safe and reliable operation in severe and critical industrial uses.
