Key Features of Stainless Steel 347 Tubes:

High Temperature Resistance: One of the primary reasons for using Stainless Steel 347 is its exceptional resistance to high-temperature environments. It can withstand temperatures up to 800-1500°C (1472-2732°F) without experiencing significant scaling or oxidation, making it ideal for applications in industries such as petrochemical, aerospace, and power generation.

Corrosion Resistance: Stainless Steel 347 contains niobium (also known as columbium), which enhances its resistance to intergranular corrosion. This property is especially important in applications where exposure to corrosive substances, such as acids, is common.

Stability in Welded Conditions: Stainless Steel 347 is well-suited for welding and maintains its properties even after being exposed to high-temperature welding processes. This makes it an excellent choice for fabricating tubes and other components that require welding.

Strength and Durability: It offers good mechanical properties, including high tensile and creep strength, which are important in structural applications where the material is subjected to mechanical stress.

Chemical Compatibility: Stainless Steel 347 is compatible with a wide range of chemicals and is often used in chemical processing industries.
