Why Stainless Steel 347 for Long Weld Neck Flanges?

Stainless Steel 347 is a niobium-stabilized austenitic stainless steel. It offers excellent resistance to corrosion and oxidation, particularly in high-temperature settings. Thanks to the niobium addition, this material is more resistant to intergranular corrosion than other grades like Stainless Steel 304 and 316. This makes Stainless Steel 347 Long Weld Neck Flanges perfect for applications that require durability at temperatures up to 1500°F.

The long weld neck design also distributes stress more effectively along the pipe, providing strength where it’s most needed. Therefore, these flanges are frequently used in high-pressure systems.

Key Features of Stainless Steel 347 Long Weld Neck Flanges

• High Temperature Resistance: Withstands temperatures up to 1500°F.
• Corrosion Resistance: Niobium-stabilized for better protection against intergranular corrosion.
• Durability: Performs well in extreme and challenging conditions.
• Enhanced Stress Distribution: The long neck reduces stress at the weld joint, offering increased strength.
