Stainless Steel 347 Flanges Corrosion Resistance

Stainless Steel 347 Flanges offer excellent resistance to intergranular corrosion caused by high temperatures. They also have outstanding resistance to oxidation and corrosion by sulfuric and hydrochloric acid environments. That makes them ideal for use in chemical and petrochemical plants where they are exposed to corrosive chemicals. Additionally, these flanges offer excellent corrosion resistance in chloride solutions and seawater, making them preferred components in marine and offshore applications.

Stainless Steel 347 Flanges Chemical Composition

Stainless Steel 347 Flanges are made of iron, chromium, and nickel. The presence of niobium in their composition enhances their resistance to intergranular corrosion. The minimum amount of chromium in Stainless Steel 347 Flanges is 17%, and the nickel content is 9%. The niobium content ranges from 10 times the amount of carbon to 1.2%, which ensures the flanges' high resistance to corrosion.
