At Hazlewood Fasteners, we proudly manufacture and supply high-performance Stainless Steel 309/309S Washers in Canberra, Australia, engineered to deliver exceptional strength, heat resistance, and corrosion protection. Designed for high-temperature environments, these washers ensure reliable fastening and load distribution even under extreme thermal stress. The combination of chromium and nickel in the 309 series provides superior oxidation resistance, while the low-carbon version, 309S, offers improved weldability and reduced carbide precipitation. Whether used in furnaces, heat exchangers, or power plants, Hazlewood’s 309/309S Washers guarantee durability and stability where precision matters most
Stainless Steel 309/309S Washers are composed of approximately 22–24% chromium and 12–15% nickel, providing exceptional resistance to oxidation and scaling up to 1000°C. The low-carbon grade 309S minimizes carbide formation, enhancing weldability and corrosion protection. These washers possess a tensile strength of around 515 MPa and yield strength of 205 MPa, maintaining integrity under mechanical and thermal loads. Their excellent creep strength, hardness, and resistance to both sulfidation and carburization make them suitable for continuous service in high-temperature and chemically aggressive environments.
