Duplex Steel Washers are top-notch fastening components crafted to work seamlessly with bolts and nuts in tough industrial and marine settings. These washers are made from duplex stainless steel, which combines austenitic and ferritic microstructures, giving them outstanding corrosion resistance, strength, and durability. Suppliers like Aria Fasteners in Hamilton, New Zealand, take great care in manufacturing these washers to ensure they have uniform thickness, smooth surfaces, and consistent dimensions. They excel at distributing load, preventing loosening from vibrations, and boosting the lifespan of bolted assemblies. This makes them a must-have in offshore, chemical, and structural applications where reliability and durability are non-negotiable.
The composition of Duplex Steel Washers is roughly equal parts austenite and ferrite, typically including iron, chromium, nickel, and molybdenum. This unique blend offers exceptional resistance to chloride-induced corrosion, pitting, and stress corrosion cracking. On the mechanical side, they showcase high tensile strength, toughness, and stability under heavy loads and high temperatures. Thanks to their corrosion resistance and mechanical performance, Duplex Steel Washers hold their ground even in harsh environments, safeguarding the fastening assembly and prolonging service life.
