The Stainless Steel 347/347H Forged Fittings are enhanced with niobium to improve their resistance to intergranular corrosion. This alloy primarily consists of chromium (17–19%), nickel (9–13%), along with small amounts of niobium and carbon. The Type 347H variant has a higher carbon content, which enhances its creep strength and stability at high temperatures. These fittings showcase impressive tensile strength (around 515 MPa), yield strength (205 MPa), and good elongation (about 40%). They maintain excellent mechanical properties even at elevated temperatures, ensuring reliable performance in thermal processing and oxidizing environments.
