Hastelloy N10276 Plate, 2.4819 Alloy C 276 Plate, Hastelloy Alloy C276 Sheet, ASTM B575 Hastelloy C276 Plate, 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 of Hastelloy N10276 Plate 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. Hastelloy C276 Plate is used in chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment and the recovery of “sour” natural gas.

ASTM B575 UNS N10276 Hastelloy C276 Sheet is frequently utilized in several industries, consisting of petrochemical, chemical oil and gas, power generation, pharmaceutical, pulp and paper manufacturing and drainage treatment. Hastelloy C276 Coil has superior resistance to matching, tension deterioration breaking as well as oxidizing environments. Hastelloy C276 Plate likewise displays resistance to deterioration by salt water in crevice conditions, which can generate hostile attack in other commonly utilized materials. Hastelloy Plate is usually remedy heat-treated at 2050 Degree F and fast quenched.

1.What are the Benefits?

Hastelloy C-276 Alloy has excellent resistance to a wide variety of chemical process environments, including:

1. Strong oxidizers (such as ferric and cupric chlorides)

2. Hot contaminated media (organic and inorganic)

3. Chlorine

4. Formic and acetic acids

5. Acetic anhydride

6. 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.
