Why Choose Stainless Steel 347 Lap Joint Flanges?

Stainless Steel 347 is an austenitic stainless steel with high chromium and columbium content. This composition makes it resistant to intergranular corrosion, which is ideal for high-temperature and corrosive environments. Consequently, it is a preferred choice in various industries.

Key Benefits:

• High Corrosion Resistance: The material resists intergranular corrosion, making it suitable for welding and high-temperature conditions.
• Temperature Tolerance: It can handle temperatures up to 1500°F (816°C) without losing its strength.
• Ease of Installation: Lap Joint Flanges are easy to align and install, which saves time and reduces costs.
• Versatility: These flanges are widely used in petrochemicals, power generation, and food processing industries.
