Duplex Steel UNS S32205 fasteners are highly versatile and used across several industries that demand durability and corrosion resistance. They perform exceptionally well in environments exposed to seawater, brine, or acidic solutions. These fasteners are widely applied in oil & gas processing, chemical plants, pulp and paper industries, and structural engineering. In marine industries, Duplex S32205 bolts and nuts prevent damage caused by saltwater exposure. Their high tensile strength allows them to withstand heavy loads and harsh operating conditions. Furthermore, these fasteners are preferred in heat exchangers, desalination plants, and water treatment systems where resistance to chloride stress cracking is essential. Their performance and long service life make Duplex S32205 fasteners a cost-effective solution for critical applications.
Duplex Steel UNS S32205 fasteners are known for their excellent combination of strength, corrosion resistance, and durability. With almost double the yield strength of standard austenitic stainless steels, these fasteners are ideal for heavy-duty applications. They also provide excellent resistance to localized corrosion such as pitting and crevice attack, especially in chloride-rich environments. The balanced microstructure of ferrite and austenite ensures improved toughness and fatigue resistance. Duplex S32205 fasteners can easily operate in a wide range of temperatures without losing strength. Their low thermal expansion rate and high resistance to erosion make them ideal for pipelines, offshore structures, and pressure vessels. Overall, their outstanding mechanical and chemical properties make them suitable for demanding industrial uses.
Duplex Steel UNS S32205 fasteners are available in various types to suit different industrial requirements. The most common forms include bolts, nuts, washers, screws, studs, and anchors. Hex bolts and heavy hex nuts are widely used in construction and oilfield industries, while machine screws and socket cap screws are chosen for precision assemblies. Washers and studs offer additional support for structural applications. Duplex S32205 fasteners are manufactured in accordance with global standards like ASTM, ASME, and DIN, ensuring compatibility with international projects. They are available in multiple finishes and sizes to meet diverse application needs. With their high strength and corrosion resistance, these fasteners serve as reliable components in chemical plants, refineries, and marine equipment.

Benefits of Duplex Steel UNS S32205 Fasteners

Using Duplex Steel UNS S32205 fasteners brings numerous benefits to industrial projects. Their high tensile and yield strength allows engineers to reduce material thickness, resulting in weight and cost savings. The outstanding resistance to corrosion in chloride-containing environments ensures long-term durability, even in seawater and aggressive chemical conditions. Duplex S32205 fasteners also provide excellent fatigue resistance, making them ideal for high-stress and vibration-prone applications. Their dual-phase microstructure enhances toughness and reduces the risk of failure under stress. Furthermore, they offer superior resistance to stress corrosion cracking compared to austenitic stainless steels. These advantages make Duplex S32205 fasteners a preferred choice for industries such as marine, oil & gas, petrochemicals, desalination, and power generation.
