What is Hastelloy C276 Plate?

This alloy is known for its corrosion resistance in a wide range of aggressive media. The high molybdenum content provides localised corrosion resistance.

Low carbon minimises carbide precipitation during welding so that heat-affected zones of welded joints are resistant to intergranular attack. In addition to chemical processing, it is also used to control pollution, produce pulp and paper, handle industrial and municipal wastes, and recover "sour" natural gas.

It can be used in air pollution control components such as stack liners, ducts, dampers, scrubbers, stack-gas re-heaters, fans, and fan housings, as well as in chemical processing components such as heat exchangers, reaction vessels, evaporators, and transfer lines.

A major benefit of these UNS N10276 Round Bars is that they do not require solution heat treatment after welding, which makes them corrosion-resistant. A variety of applications are possible for these alloys, including chemical process equipment and flue gas desulfurization equipment. Although they can be machinable, the alloy work hardens as most nickel-base alloys do. Various diameters, wall thicknesses, and sizes are available to our valued customers at very reasonable prices c276, c276 hastelloy, what is hastelloy, hastelloy c276.

Characteristics

Its nickel alloy properties have been attributed to Hastelloy Alloy Round Bars being used in harsh environments. In addition to nickel and chromium, there is also tungsten and iron in controlled amounts, as well as a low carbon content. Carbide deposition is minimised during heat treatment and welding when the carbon content is low.

When used in welded systems, the metal retains excellent resistance to pitting and crevice corrosion. When other materials are heated during welding, they become weaker, making them more corrosion resistant. Corrosion resistance is one of the material’s main features. In spite of harsh conditions, this material is extremely resistant to corrosion, including stress corrosion cracking, pitting, and crevice corrosion.

There are several materials that are extremely resistant to this, including sulfuric, hydrochloric, and phosphoric acids, severely oxidising, acidic, and acid chlorides, and solvents such as conventional and acetic acids, acetic anhydride, liquid chlorine gas, hypochlorites, and chlorine solutions. Because of its high resistance to corrosion caused by seawater, Hastelloy C276 Round Bars are widely used in the chemical processing industry.

Applications

There are a number of applications for these alloys, such as chemical process equipment and flue gas desulfurization equipment. The alloy is also machinable, but it hardens like most nickel-base alloys. We offer these at affordable prices in a wide variety of diameters, walls, and sizes.

Hastelloy C-276 is a nickel-chromium-molybdenum alloy with unsurpassed corrosion resistance worldwide. It is resistant to a wide range of chemical process conditions, including ferric and cupric chlorides, hot contaminated mineral acids, solvents, chlorine, and chlorine contaminated environments (both organic and inorganic), Hypochlorite and chlorine dioxide solutions, dry chlorine, formic and acetic acids, acetic anhydride, seawater and brine solutions, and hypochlorite and chlorine dioxide solutions In the as-welded condition, Alloy C276 resists the production of grain boundary precipitates in the weld heat-affected zone, making it suitable for most chemical operations. It has good pitting and stress corrosion cracking resistance.

Fabrication and heat treatment

A Hastelloy C276 machine can be operated in the same manner as an iron-based alloy. Commercial coolants are used for machining operations. Water-based coolants are used for grinding, milling, and turning operations at high speeds. Hastelloy C276 can be welded using gas-tungsten arc welding, shielded metal arc welding, gas metal arc welding, and submerged arc welding.

Conclusion

Due to its outstanding corrosion resistance to a wide range of hostile media, Hastelloy C276 Round Bars are a product worth considering for a demanding environment like this one. As one of the most adaptable alternatives to severe conditions, it is used in a wide range of manufacturing applications.

A high molybdenum content in Hastelloy C276 Round Bars makes them resistant to pitting and crevice corrosion. These materials are used in waste fluid treatment systems that require harsh conditions that other materials may not be able to handle.

A number of chemical processing applications require Hastelloy C276 Round bars, including ferric and cupric chloride ions, chlorine, hypochlorite, chlorine dioxide, organic acids, acetic anhydride, seawater, brine, and sour oil and gas fields.
