Adam Stainless is your go-to source for top-notch **Stainless Steel 348 fasteners**, proudly manufactured and supplied from Canberra, Australia. These fasteners are crafted to excel in high-temperature and corrosive settings, ensuring outstanding performance. Each piece is precision-engineered to meet international standards, which means you can count on accurate threading, consistent quality, and impressive mechanical strength. With their remarkable stability and resistance to oxidation, Adam Stainless’s Stainless Steel 348 fasteners guarantee secure and durable connections for those tough industrial applications where reliability is a must.
Made from an austenitic stainless steel alloy, Stainless Steel 348 fasteners contain around 18% chromium, 8–11% nickel, and trace amounts of niobium (columbium) and tantalum. These elements work together to prevent carbide precipitation and intergranular corrosion, especially when exposed to high temperatures for extended periods. On the mechanical side, Stainless Steel 348 boasts a tensile strength ranging from 515 to 620 MPa and a yield strength close to 205 MPa, along with excellent creep resistance and oxidation stability up to 900°C, plus good formability and weldability.
