Manufacturing Process
Flanges are hot or cold forged to ensure structural integrity.
Post-forging heat treatment (solution annealing) to optimize corrosion resistance and mechanical properties.
What are the characteristics of Hastelloy C276?
1. Excellent corrosion resistance in reducing environments
2. Exceptional resistance to strong solutions of oxidizing salts, such as ferric and cupric chlorides
3. High nickel and molybdenum contents providing good corrosion resistance in reducing environments
4. Low carbon content which minimizes grain-boundary carbide precipitation during welding to maintain resistance to corrosion in heat-affected zones of welded joints
5. Resistance to localized corrosion such as pitting and stress-corrosion cracking
6. One of few materials to withstand the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide
Applications
Industries:
Chemical & Petrochemical: Reactors, pipelines, acid storage.
Oil & Gas: Offshore platforms, sour gas environments (H₂S).
Marine: Seawater handling systems.
Pharmaceuticals: Aggressive chemical processing.
Pollution Control: Flue gas desulfurization (FGD) systems.
Common Uses:
Connecting pipes in corrosive or high-temperature systems.
Critical junctions in chlorine, bleach, and sulfuric acid plants.
