Looking for top-notch **Stainless Steel 347H flanges**? Adam Stainless has you covered! Based in Canberra, Australia, we specialize in high-quality flanges designed to deliver exceptional strength, corrosion resistance, and outstanding performance even in high-temperature settings. Our flanges are crafted to meet international standards, ensuring precise dimensions, smooth finishes, and dependable sealing capabilities. Whether you’re dealing with critical piping or pressure vessel applications, our Stainless Steel 347H flanges are perfect for situations where thermal stability and resistance to intergranular corrosion are a must.
So, what makes Stainless Steel 347H special? This austenitic stainless steel alloy boasts around 17–19% chromium, 9–13% nickel, and is stabilized with niobium (columbium) to prevent carbide precipitation. The higher carbon content enhances creep strength and mechanical stability, allowing it to withstand temperatures up to 925°C, while niobium boosts resistance to intergranular corrosion. On the mechanical side, these flanges provide a tensile strength ranging from 515 to 620 MPa and a yield strength of about 205 MPa, along with excellent oxidation resistance.
