What is Hastelloy C276 Flanges?
Hastelloy C276 flanges are superalloys that perform well across different systems. The flanges are designed with a superior concentration of nickel, chromium, and molybdenum with small additions of tungsten. The content embedded in this grade gives them enhanced corrosion and oxidation resistance across stress-induced environments. The flanges securely seal a range of piping equipment in the system. The grade of flanges can be shaped in different sizes and can be welded following standard welding procedures.

ASTM B564 UNS N10276 Slip on Flange Vs Nickel C276 Lap Joint Flange
Lap joint and slip on flanges are versatile grades in the C276 alloy grade. Both these flanges can be distinguished from key features.
- ASTM B564 UNS N10276 Slip on the flange is slid on a piping grade and welded using one or more fillet welds. A Nickel C276 Lap Joint flange consists of a backing flange and a stub end which are welded in place using a butt-weld.
- Lap joint flanges are utilized in high-pressure applications. Slip on flange is a flange of choice in low pressure applications.
