Here’s the text we’re looking at: Adam Stainless offers top-notch **Stainless Steel 348 nuts** right from Canberra, Australia. These nuts are designed for outstanding strength, heat resistance, and corrosion performance. Each one is crafted with precision to meet international quality standards, guaranteeing accurate threading, a smooth surface finish, and exceptional mechanical reliability. Adam Stainless’s Stainless Steel 348 nuts are perfect for fastening in high-temperature and corrosive settings, where structural stability and oxidation resistance are a must.
These nuts are made from an austenitic stainless steel alloy that includes about 18% chromium, 8–11% nickel, along with small amounts of niobium (columbium) and tantalum. These stabilizing elements boost resistance to intergranular corrosion and help prevent carbide precipitation during extended heating. The alloy boasts a tensile strength of around 515–620 MPa and a yield strength close to 205 MPa, maintaining impressive creep and oxidation resistance up to about 900°C. Plus, it offers good weldability and toughness, even at higher temperatures.
