Advantages of EN 10222-5 1.4571 (316Ti) Forged Ring & Flange

Superior Strength & Durability: The forging process creates a dense, uniform grain structure, making these flanges significantly stronger and more durable than cast alternatives. They are ideal for high-pressure and high-stress applications

Excellent Corrosion Resistance: Made from 1.4571 (316Ti) stainless steel, these flanges offer excellent resistance to corrosion, particularly in challenging environments containing chemicals or chlorides

Reliable Performance in High-Temperature Service: The flanges maintain their mechanical properties and structural integrity at elevated temperatures, making them suitable for power generation and petrochemical applications

Precise Dimensions for a Secure Fit: The manufacturing process ensures tight dimensional tolerances, which facilitates easier installation and helps achieve leak-proof connections in piping systems

Long-Term Cost-Effectiveness: While the initial cost may be higher, their extended service life, reduced need for maintenance, and high reliability make them a cost-effective choice over time
