So, what exactly is Stainless Steel 347? It’s an austenitic stainless steel alloy that boasts around 17–19% chromium, 9–13% nickel, and is stabilized with niobium (columbium). This clever addition of niobium helps prevent carbide precipitation during welding and extended heating, which greatly enhances resistance to intergranular corrosion. With a tensile strength ranging from 515 to 620 MPa and a yield strength close to 205 MPa, this alloy maintains excellent oxidation resistance up to 900°C, along with remarkable mechanical stability and weldability.

Stainless Steel 347 Flanges Uses

SS 347 Flanges are widely used in industries having high corrosion resistance and heat stability. Especially in chemical processing, petrochemical and power generation plants, stainless steel 347 flanges are most suitable for high temperature applications. Stainless Steel 347 is also resistance to intergranular corrosion, so it is used in welded structures. These flanges are widely used in the aerospace industry, food processing, and pharmaceutical sectors because of their durability and resistance to oxidation. They are also used in heat exchangers, reactors, and pressure vessels, where their strength, weldability, and resistance to scaling under high-temperature conditions are essential.
