At Hazlewood Fasteners in Canberra, Australia, our Duplex steel washers are built for environments where corrosion pressure, structural force, and relentless mechanical stress converge. Crafted from a formidable dual-phase microstructure, these washers deliver enhanced load distribution and surface protection in assemblies facing harsh industrial realities. They stand resilient where traditional stainless steels fatigue — from salt-heavy marine applications to corrosive chemical operations. When your equipment demands washers that defend against surface wear, crevice attack, and high-stress vibration, Hazlewood’s Duplex steel washers provide uncompromising stability, extending component life and fortifying your fastening system with exceptional endurance.
Duplex steel washers combine a balanced ferritic-austenitic alloy matrix enriched with chromium, molybdenum, and nitrogen, giving them superior strength and corrosion resistance. Nearly twice as strong as standard stainless grades, they offer exceptional resistance to pitting, crevice corrosion, and chloride-induced stress cracking. Their metallurgical toughness ensures reliable preload retention, reduced deformation, and long-term resistance to abrasive forces and chemical exposure. Designed to support heavy-duty clamping forces in aggressive environments, Duplex washers deliver unmatched durability and mechanical stability under both static and dynamic loading conditions.

Duplex steel washers are the preferred choice for fastening systems exposed to marine, offshore, chemical, and industrial extremes. They enhance joint reliability in desalination plants, oil & gas platforms, shipyards, chemical processing units, paper-pulp systems, and high-stress mechanical assemblies. Used with pumps, heat exchangers, pressure vessels, pipe flanges, and coastal structural frameworks, they prevent bolt embedding, protect mating surfaces, and ensure structural alignment under intense load and vibration. When installations demand washers that battle salt, corrosion, heavy pressure, and abrasive wear without compromise, Duplex steel washers deliver steadfast, long-life protection and fastening confidence.
