Stainless Steel 347/347H Buttweld Fittings are stabilized austenitic stainless steels with chromium, nickel, and niobium (columbium) content, which provides resistance to intergranular corrosion after exposure to high temperatures. Grade 347H contains higher carbon for enhanced strength and creep resistance at elevated temperature service. These fittings are generally providing tensile strength of about 515 MPa and yield strength of about 205 MPa. They have very good mechanical properties up to service temperatures of 870°C, hence used where thermal cycling and long-term exposure to heat are involved.
