What is Inconel 600 Nickel Alloy Flange?
Inconel 600 Nickel Alloy Flange is a high-performance industrial flange made from Inconel 600 (UNS N06600), a nickel-chromium-iron alloy. It is known for excellent resistance to heat, corrosion, and oxidation, making it ideal for harsh environments like chemical processing, power generation, and marine applications. These flanges maintain strength and stability in high-temperature and corrosive conditions.
When to Choose Inconel 600 Over Other Materials
| Use Case | Why Inconel 600? |
|---|---|
| High-temperature service | Withstands heat better than most stainless steels |
| Corrosive chemical environments | Superior resistance to acids and chlorides |
| Thermal cycling | Excellent fatigue resistance and dimensional stability |
| Nuclear/energy sectors | Good radiation resistance and low corrosion under neutron flux |
