Super Duplex Steel Fasteners are high-strength mechanical components that join or fasten two or more parts together in various industrial applications. They are made from stainless steel, known as “super duplex,” a highly corrosion-resistant and durable material. Super duplex stainless steel is characterized by its dual-phase microstructure, consisting of both austenitic and ferritic phases, and it offers superior mechanical properties compared to conventional stainless steel.

Advantages of Super Duplex Steel Fasteners

  1. Excellent Corrosion Resistance: Super Duplex Steel Fasteners offer superior corrosion resistance to standard stainless steel fasteners, particularly in aggressive environments containing chlorides, acids, and seawater.
  2. High Strength: They possess higher tensile and yield strength than conventional stainless steel fasteners, providing increased load-bearing capacity and structural integrity.
  3. Enhanced Toughness: Super Duplex Steel Fasteners exhibit improved toughness and flexibility, making them less prone to brittle fracture under high-stress conditions.
  4. Resistance to Pitting and Crevice Corrosion: They provide excellent resistance to pitting and crevice corrosion, common forms of localized corrosion in corrosive environments.
  5. Stress Corrosion Cracking (SCC) Resistance: These fasteners are highly resistant to stress corrosion cracking, which occurs under combined tensile stress and corrosive conditions.
  6. Suitability for High-Temperature Applications: Super Duplex Steel Fasteners maintain their mechanical properties at elevated temperatures, making them suitable for high-temperature applications such as heat exchangers and processing equipment.
  7. Versatility: They can be used in various industries and applications, including offshore oil and gas, marine, chemical processing, desalination, and power generation, due to their exceptional corrosion resistance and mechanical properties.
  8. Longevity and Durability: Super Duplex Steel Fasteners have a longer service life and require less maintenance than standard stainless steel fasteners, resulting in cost savings over time.
