Characteristics of Duplex Steel Fasteners

High Strength: Duplex steel fasteners exhibit superior strength compared to conventional stainless steel fasteners. The combination of austenite and ferrite phases provides enhanced tensile and yield strength, making them suitable for demanding applications that require high load-bearing capacity.

Corrosion Resistance: Duplex steel fasteners offer excellent corrosion resistance, particularly in aggressive environments such as seawater, chloride-containing solutions, and acidic conditions. The presence of chromium, molybdenum, and nitrogen in the alloy composition provides resistance to localized corrosion, including pitting and crevice corrosion.

Excellent Toughness: Duplex steel fasteners possess excellent toughness, enabling them to withstand impact, vibration, and dynamic loading conditions. This toughness makes them highly suitable for applications where resistance to stress corrosion cracking and fatigue failure is crucial.

Good Weldability: Duplex steel fasteners have good weldability, allowing for easy fabrication and installation. They can be welded using various methods, such as shielded metal arc welding, gas tungsten arc welding, and plasma arc welding, without compromising their corrosion resistance and mechanical properties.

Types of Duplex Steel Fasteners

Duplex Steel Bolts: These fasteners are used to join two or more components together and provide a secure and reliable connection. Duplex steel bolts are available in various head styles, such as hexagon, socket, and countersunk, to accommodate different application requirements.

Duplex Steel Nuts: Nuts are used in conjunction with bolts to fasten components. Duplex steel nuts offer excellent corrosion resistance and high strength, ensuring reliable and durable connections.

Duplex Steel Screws: Screws are versatile fasteners used for a wide range of applications. Duplex steel screws provide strong and secure fastening in corrosive environments, making them suitable for industries such as chemical processing, offshore, and marine.

Duplex Steel Studs: Studs are threaded rods without a head and are used to fasten components by being threaded into a nut. Duplex steel studs offer the same high strength and corrosion resistance as other duplex steel fasteners.

Advantages of Duplex Steel Fasteners

Strength and Durability: The high strength and toughness of duplex steel fasteners make them suitable for heavy-duty applications where reliability and longevity are essential. They can withstand high mechanical stress and provide long-term performance even in harsh environments.

Corrosion Resistance: Duplex steel fasteners offer superior corrosion resistance compared to standard stainless steel fasteners. This makes them particularly beneficial in industries such as offshore oil and gas, marine, chemical processing, and desalination plants, where exposure to corrosive substances is prevalent.

Cost-Effectiveness: Despite their enhanced properties, duplex steel fasteners can be a cost-effective choice. Their long service life, resistance to corrosion, and reduced maintenance requirements contribute to overall cost savings over time.

Applications of Duplex Fasteners

Oil and Gas Industry: Duplex steel fasteners find extensive use in offshore oil platforms, subsea installations, and oil refineries due to their excellent corrosion resistance, strength, and resistance to stress corrosion cracking.

Chemical Processing: Duplex steel fasteners are widely employed in chemical processing plants, where they are exposed to aggressive chemicals, high temperatures, and corrosive environments.

Desalination Plants: Duplex steel fasteners are suitable for desalination plants where they are exposed to seawater and high chloride concentrations. Their corrosion resistance makes them ideal for critical components in the desalination process.

Marine Applications: Duplex steel fasteners are used in various marine applications, including shipbuilding, offshore structures, and seawater handling equipment, thanks to their ability to withstand the harsh marine environment.

Pulp and Paper Industry: Duplex steel fasteners are utilized in pulp and paper mills, where they are exposed to corrosive chemicals, high temperatures, and mechanical stress.
