The Hastelloy C276 foil is known to be a premium metal alloy with high corrosion resistance properties. Although available also in sheet ad rolls, its foil option is often preferred where the thickness could range between .0005 and .0079 inches. Thicker versions would be considered sheets up to .0125 inch.
It is categorized as a super-alloy or high-performance alloy due to this dynamic property which is highly demanded in many applications.
Basic Dynamics
The basic material in this dynamic metal alloy is its high content of Molybdenum that brings out the high resistance to pitting and corrosion in crevices. Its primary alloying ingredient is the transition nickel with varying percentages of chromium, cobalt, copper, iron, manganese, aluminum, titanium, carbon, zirconium and tungsten.
A Hastelloy super alloy could come in various forms with different properties but its attractive feature is its ability to perform excellently in high-temperature, high-stress environments with a strong resistance to corrosion. It is known to be an effective alloy in erosion-prone environments where iron-based alloys have failed.
Hence, the Hastelloy C276 foil could be found in the pressure vessels of nuclear and chemical reactors as well as distillation equipment, valves and pipes in the chemical industry. However, there is a potential for this metal alloy to experience degradation if poor fabrication and handling occur. Nevertheless, its strength could be safeguarded with electro-polishing or passivity.
Characteristics
The Hastelloy C276 foil is an excellent choice in most chemical process applications. It is versatile in welded conditions with a high resistance to pitting and oxidation to withstand extreme temperatures up to 1900°F.
This is one of the few metal alloys that are known to resist wet chloride gas and hypochlorite solution as well as chlorine dioxide solution. It is also resistant to concentrated oxidizing salts without conforming to grain boundary precipitation.
Industrial Applications
The Hastelloy C276 foil, tube, sheet or bar makes amazing digesters in the paper industry. Another typical application is the equipment components which are engaged in petrochemical organic chloride processes. Many chemical processes which utilize halide or acid catalysts also require this metal alloy foil to be successful.
Pulp and paper in bleach plants often deploy Hastelloy C276 foil or sheet besides scrubbers and food processing equipment. The metal alloy is excellent ducting material for the desulfurization of flue gas desulfurization. It is widely applied in the pharmaceutical industry.
Conclusion
The list of applications for Hastelloy C276 is unlimited in foil, sheet or roll form.
