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.

Stainless Steel 347H Flanges Uses

Stainless Steel 347H Flanges are used in very high stress and also under high-temperature conditions. It is highly resistant to corrosion and oxidation. It is used in chemical processing, refineries, and power plants where temperatures are at high levels with extra harsh condition. The added columbium and tantalum increase stability and sensitize to resistance so that there will be no intergranular corrosion. In other industries, the 347H flanges are used in the equipment, like boilers, heat exchangers, and reactors in petrochemical, pharmaceutical, and food processing industries. This makes them the choice for extreme application in critical use in several fields.
