Product Selection Differences for 347 Grade Stainless Steel

When selecting 347 grade stainless steel, some key differences to consider compared to other grades include:

1. Composition: 347 stainless steel contains higher amounts of chromium, nickel, and columbium (also known as niobium) compared to other stainless steel grades. This composition provides increased resistance to intergranular corrosion and high temperatures.

2. Corrosion Resistance: 347 stainless steel offers improved corrosion resistance in high-temperature applications, making it suitable for applications in environments with exposure to corrosive chemicals or high temperatures.

3. High Temperature Performance: 347 stainless steel is known for its excellent performance at elevated temperatures, making it a preferred choice for applications where high-temperature resistance is critical, such as in the aerospace, chemical processing, and thermal processing industries.

4. Weldability: 347 stainless steel is easily welded and processed compared to some other stainless steel grades, making it suitable for fabrication and welding operations.

5. Heat Resistance: The columbium content in 347 stainless steel provides enhanced resistance to carbide precipitation during welding or high-temperature exposure, reducing the risk of intergranular corrosion.

6. Application: Due to its high-temperature resistance and corrosion-resistant properties, 347 stainless steel is commonly used in applications such as heat exchangers, chemical processing equipment, jet engine components, and other high-temperature applications.

When selecting 347 grade stainless steel, carefully consider these factors to ensure it meets the requirements of your specific application.
