Stainless Steel 347 Flanges are an excellent choice for applications requiring high corrosion resistance, mechanical strength, and heat resistance. They are durable, easy to fabricate and install, and offer outstanding resistance to intergranular corrosion. Their chemical composition and physical properties make them a preferred choice for various industries, including oil and gas, chemical, marine, and petrochemical.
Stainless Steel 347 Flanges features
Stainless Steel 347 flanges offer many benefits, including high resistance to intergranular corrosion, outstanding mechanical properties, and excellent chemical resistance. They are heat resistant and have good tensile strength. The flanges are available in different sizes, shapes, and dimensions to meet different needs. The flanges are also highly durable and can withstand tough environments. They have excellent weldability, making them easy to fabricate and install. These features make Stainless Steel 347 Flanges popular for high-temperature applications in chemical plants, refineries, and other harsh environments..

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.
Stainless Steel 347 Flanges Physical & Mechanical Properties
Stainless Steel 347 Flanges have exceptional physical and mechanical properties. They have a melting point of 2550-2635°F, density of 0.288 lb/in^3, Young's modulus of 28 x 10^6 psi, and thermal conductivity of 9.0 Btu/hr-ft-°F. The tensile strength of these flanges is 75 ksi, the yield strength is 30 ksi, and the elongation is 40%. These properties make them ideal for applications requiring high temperatures and mechanical strength.
