ASTM B564 Hastelloy C22 Flanges are high-performance nickel alloy flanges designed for extreme corrosion resistance in harsh chemical, marine, and high-temperature environments. Made from UNS N06022 / Werkstoff Nr. 2.4602, these flanges offer excellent protection against pitting, crevice corrosion, and stress corrosion cracking. They are widely used in industries such as chemical processing, power generation, and offshore engineering.
What Are Hastelloy C22 Flanges?
Hastelloy C22 Flanges are forged pipe connection components manufactured as per ASTM B564 Hastelloy C22 Flanges and ASME SB564 Hastelloy C22 Forge Flange standards. These flanges are made from a nickel-chromium-molybdenum alloy known for its superior corrosion resistance across both oxidizing and reducing environments.
Unlike standard stainless steel flanges, Hastelloy C22 offers:
- Exceptional resistance to aggressive chemicals
- Stability in high-temperature conditions
- Long service life with minimal maintenance
We supply a wide range of configurations including ASME SB564 Hastelloy C22 Weld Neck Flange, ASTM B564 Hastelloy C22 Threaded Flange, and ASTM B564 Hastelloy C22 Square Flange to suit various industrial requirements.
