Advantages of Stainless Steel 347 Flanges

  • High-Temperature Resistance: Stainless steel 347 is designed for high-temperature applications and provides excellent resistance to intergranular corrosion and oxidation at temperatures up to 800-1500°F (427-816°C). This provides 347 flanges that are suitable for use in areas where high temperatures are a concern, such as in heat exchangers, refinery furnaces, and high-temperature machinery.

  • Easy to manufacture: Stainless steel 347 is extremely easy to manufacture, welded and fabricated, allowing for complex shapes and structures with accurate dimensions and tight tolerances. This makes it easy to install, locate and repair, reducing overall costs and downtime.

  • Strength and durability: 347 stainless steel retains its mechanical properties at high temperatures, providing excellent strength and durability even in extreme conditions. This makes 347 flanges strong and reliable for use in complex applications where technical integrity is critical.

  • Chemical stability: Stainless steel 347 is stabilized with niobium (columbium), enhancing this intergranular corrosion resistance. This stabilizer makes it suitable for use in corrosive chemical environments or where chemical controls are common, such as chemical plants and oil refineries.

  • Corrosion resistance: Like other stainless steel alloys, 347 exhibits excellent corrosion resistance compared to many other materials. Containing chromium and nickel, it forms an inert oxide on the steel surface, providing corrosion protection in harsh environments under high acid and chloride conditions.

How to Choose the Right Stainless Steel 347 Flanges

  • Corrosion Resistance: Stainless Steel 347 is designed for intergranular corrosion resistance, making it suitable for expected applications in corrosive environments. It ensures that the flange you choose has sufficient corrosion resistance for your specific operating conditions.

  • Size and thickness: Choose flanges that match the thickness and thickness of your piping system or appliance. Make sure the flange has the correct bore size, thickness, and bolt-hole configuration for easy installation and proper assembly.

  • Stress Analysis: Consider the stress levels of stainless steel 347 flanges to ensure they can withstand your system’s stress conditions without risk of failure or drop. Compare the pressure in the flange to your piping or equipment needs.

  • Thermal Resistance: Stainless steel 347 provides excellent resistance to high temperatures, making it suitable for high-temperature applications such as heat exchangers, boilers, air filters, etc. Ensure that the flanges can withstand the heat of your application without compromising their mechanical properties.

Are Stainless Steel 347 Flanges weldable?

Yes, Stainless Steel 347 flanges are weldable. They exhibit good weldability using common welding methods such as shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), and gas metal arc welding (GMAW). Preheating and post-weld heat treatment may be required to prevent sensitization and maintain corrosion resistance.

FAQ (Frequently Asked Questions)

Can Stainless Steel 347 flanges be recycled after use?

Yes, Stainless Steel 347 flanges can be recycled after use. Stainless steel is highly recyclable and retains its properties even after multiple recycling processes. Recycling helps conserve natural resources, reduces energy consumption, and minimizes environmental impact, making it an environmentally sustainable choice.

Are Stainless Steel 347 flanges suitable for cryogenic applications?

Stainless Steel 347 flanges are generally not recommended for cryogenic applications due to reduced toughness at low temperatures. While they offer good corrosion resistance and high-temperature performance, their impact strength may be compromised in cryogenic conditions. Alternate stainless steel grades like 304L or 316L are more suitable for cryogenic applications.

Can Stainless Steel 347 flanges be used for underground applications?

Stainless Steel 347 flanges can be used for underground applications with proper precautions. They offer good corrosion resistance, but protection against soil conditions and moisture is essential to prevent corrosion. Coating the flanges or using corrosion-resistant backfill materials can enhance their durability and longevity underground.
