Adam Stainless is your go-to source for top-notch **Stainless Steel 405 nuts**, proudly manufactured in Canberra, Australia. These nuts are designed with strength, heat resistance, and durability in mind. Each one is crafted to meet international standards, guaranteeing precise threading, a smooth finish, and consistent quality. Whether you’re dealing with moderate corrosion, oxidation, or high temperatures, Adam Stainless’s Stainless Steel 405 nuts deliver reliable fastening solutions that strike a perfect balance between performance and cost.
Made from a ferritic stainless steel alloy that contains about 11.5–14.5% chromium and a touch of aluminum, these nuts boast enhanced oxidation resistance and prevent hardening during heat treatment. This unique composition provides excellent corrosion and scaling resistance, especially in mildly corrosive and high-temperature settings. On the mechanical side, Stainless Steel 405 offers a tensile strength of around 450 MPa and a yield strength of about 205 MPa, along with impressive thermal stability and moderate ductility.
