Features of Stainless Steel 347 Welded Pipe

Excellent Corrosion Resistance: Stainless Steel 347 is highly resistant to corrosion, especially in harsh environments like sulfuric acid and high-temperature gases.
Superior High-Temperature Performance: It works well at high temperatures, making it perfect for heat exchangers, boilers and similar applications.
Good Weldability: Thanks to columbium, Stainless Steel 347 is easy to weld, ensuring strong and reliable joints.
Resistance to Intergranular Corrosion: The columbium addition helps prevent carbide buildup, making it resistant to intergranular corrosion.
Durability and Strength: Stainless Steel 347 welded pipe is strong and durable, even in tough, high-temperature conditions.

We supply SS 347 welded pipes, which offer excellent resistance to oxidation, carburization and intergranular corrosion in high-temperature settings. These pipes are widely used in industries like aerospace, chemical processing and petrochemicals for applications such as heat exchangers and exhaust systems. Their strong resistance to sensitization makes them ideal for welded structures exposed to high heat. They also perform well in sulfur-rich environments and are perfect for power plants and furnace applications where heat resistance is key.
