1.What is Hastelloy C276 Plate?
Alloy C-276 (UNS N10276, W.Nr. 2.4819) is known for its corrosion resistance in a wide range of aggressive media. The high molybdenum content imparts resistance to localized corrosion such as pitting.
The low carbon minimizes carbide precipitation during welding to maintain resistance to intergranular attack in heat-affected zones of welded joints. It's used in chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment and the recovery of “sour” natural gas.
Applications in air pollution control include stack liners, ducts, dampers, scrubbers, stack-gas re-heaters, fans and fan housings. In chemical processing, the alloy is used for components including heat exchangers, reaction vessels, evaporators and transfer piping
2.What are the Benefits?
Hastelloy C-276 Alloy has excellent resistance to a wide variety of chemical process environments, including :
- Strong oxidizers (such as ferric and cupric chlorides)
- Hot contaminated media (organic and inorganic)
- Chlorine
- Formic and acetic acids
- Acetic anhydride
- Seawater and brine solutions
Moreover, it's used in flue gas desulfurization systems because of its excellent resistance to sulfur compounds and chloride ions encountered in most scrubbers. The product, such as Hastelloy C-276 pipe, also has excellent resistance to pitting and to stress-corrosion cracking. It's one of the few materials that withstands the corrosive effects of wet chlorine gas, hypochlorite, and chlorine dioxide.
