Stainless Steel 347 Round Bar is a solid cylindrical metal bar manufactured from the Stainless Steel 347 alloy. Stainless Steel 347 is an austenitic stainless steel alloy identical to Stainless Steel 321 that has been stabilized with niobium (also known as columbium) to avoid carbide precipitation during welding and exposure to high temperatures. This stabilization improves the alloy's corrosion resistance, especially in sensitizing conditions where intergranular corrosion might occur. Stainless Steel 347 Round Bar has outstanding high-temperature strength, oxidation resistance, and weldability, making it appropriate for various applications in sectors like aerospace, chemical processing, and automotive.

347 Stainless Steel Round Bar is classified as high temperature because of its ability to maintain mechanical strength, corrosion resistance, and structural integrity at high temperatures. The particular high-temperature range varies depending on the application and ambient circumstances, but 347 Stainless Steel Round Bar can typically tolerate temperatures ranging from 800°C to 900°C (1472°F to 1652°F) in continuous service. Beyond this range, its performance may be influenced by oxidation, creep, and thermal expansion. However, with adequate stabilization and heat treatment, 347 Stainless Steel Round Bar may resist sensitization and intergranular corrosion, making it acceptable for use in high-temperature applications such as exhaust systems, heat exchangers, and thermal processing equipment.

347 Stainless Steel Round Bar is widely utilized in various sectors due to its excellent qualities. It is used in aircraft for exhaust systems and engine components, chemical processing for reactors and pipelines containing corrosive chemicals, and food processing for gear that requires cleanliness and corrosion resistance. It's also used in automobile exhaust systems, heat exchangers for thermal processing, and petrochemical equipment to handle corrosive fluids. Its flexibility extends to thermal processing equipment and pharmaceutical gear, making it vital in applications requiring corrosion resistance, high-temperature strength, and weldability.
