Looking for top-notch **Stainless Steel 347 pipes**? Adam Stainless has you covered! Based in Canberra, Australia, we provide high-quality pipes designed to withstand the toughest industrial conditions. Our Stainless Steel 347 pipes are built for exceptional corrosion resistance, heat stability, and mechanical strength, making them perfect for demanding environments. Manufactured to meet international standards, these pipes feature precise dimensions, smooth internal finishes, and excellent weldability, ensuring they perform reliably and last long.
So, what’s special about Stainless Steel 347? It’s an austenitic stainless steel alloy that contains around 17–19% chromium and 9–13% nickel, with niobium added to prevent carbide precipitation and boost resistance to intergranular corrosion—especially after welding or when exposed to high temperatures. This alloy boasts a tensile strength of 515 to 620 MPa and a yield strength close to 205 MPa, along with impressive oxidation resistance up to 900°C, all while maintaining toughness and stability under extreme conditions.
