At Hazlewood Fasteners in Canberra, Australia, our Duplex Steel 2205 nuts are the armor choice for environments where corrosion, stress, and fatigue relentlessly battle metal integrity. Built from a dual-phase microstructure that blends strength with resilience, these nuts outperform standard stainless in chloride-rich, high-pressure, and industrially aggressive zones. From chemical refineries to offshore decks and demanding mechanical systems, they hold firm where ordinary hardware surrenders. When your infrastructure must withstand salt, acids, vibration, and time itself, Hazlewood’s Duplex 2205 nuts deliver dominating fastening confidence and enduring structural assurance — forged for the harsh, the heavy, and the high-stakes.
Duplex 2205 nuts are crafted from a balanced ferritic-austenitic stainless steel, enriched with chromium, molybdenum, and nitrogen for exceptional corrosion resistance and mechanical strength. They deliver elevated yield strength nearly double that of standard austenitic stainless steels, alongside superior resistance to pitting, crevice corrosion, and stress-corrosion cracking. These nuts maintain structural stability under dynamic loads, cyclic stress, and harsh chemical exposure. With robust tensile power, tough ductility, and remarkable endurance against chloride attack, Duplex 2205 nuts ensure secure fastening in environments that punish conventional stainless steel.

To satisfy our clients needs by providing high quality products at competitive price as per the schedule and to maintain long term relationship with our clients.
Duplex Steel 2205 nuts excel in environments where seawater, chemicals, and mechanical stress collide. They are trusted across offshore rigs, desalination systems, marine engineering, chemical processing units, pulp-and-paper facilities, wastewater treatment plants, mining operations, and pressure-piping installations. Ideal for pumps, heat exchangers, flanges, machinery housings, structural frames, and heavy duty bolting systems, they support equipment subjected to corrosive attack and operational vibration. When your engineering demands require higher strength than 316 stainless and greater corrosion resilience than carbon steel, Duplex 2205 nuts deliver lasting fastening performance and industrial-grade dependability.
