Stainless Steel 309H Flanges are composed mainly of Nickel (12–15%), Chromium (22–24%), Carbon (0.04–0.10%), along with Manganese, Silicon, Phosphorus, and Sulfur in controlled amounts. These elements enhance strength, oxidation resistance, and heat tolerance. The mechanical properties include a tensile strength of 515 MPa (min), yield strength of 205 MPa (min), and elongation of 40% (min). With excellent toughness and stability at elevated temperatures, 309H flanges are ideal for high-temperature, high-pressure, and corrosive industrial applications.
