Hastelloy C276 Wire: Unmatched Performance in Corrosive and High-Temperature Environments

Hastelloy C276 Wire: The High-Performance Material for Corrosive and High-Temperature Applications

In industrial settings where high temperatures, highly corrosive environments, and aggressive media are ubiquitous, materials that can withstand harsh working conditions are essential. One such high-performance material is Hastelloy C276 wire, a nickel-molybdenum-chromium alloy with superior strength, corrosion resistance, and flexibility. In this blog, we’ll explore why Hastelloy C276 wire is a go-to material for industries ranging from chemical to aerospace.

What are Hastelloy C276 Wire?

Hastelloy C276 wire is a nickel-chromium-molybdenum alloy with superior corrosion resistance in harsh environments. The wire protects against pitting, crevice corrosion, and stress corrosion cracking. It has higher chromium levels than other alloys, so it forms an impermeable oxide layer on the surface of the wire that prevents further deterioration from environmental factors. Hastelloy C276 also excels in high-temperature applications thanks to its ability to resist oxidation at temperatures up to 2000° F (1093° C). In addition, it has outstanding weld ability and fabric ability properties, making it ideal for welding and fabrication projects. Its general uses include the construction of valves for acidic environments, such as seawater pumps or pressure vessels made from chlorinated media or sulfuric acid mixtures. Furthermore, this material is highly malleable, so it can be easily formed into complex shapes using simple tools without losing strength. Therefore, it can be used to manufacture several types of products, including tanks and other containers for corrosive chemical elements and electric cables conducting harsh conditions like off-shore platforms or power plants with sea water as a coolant medium

Advantages of Hastelloy C276 Wire

Composition and Properties

Hastelloy C276 wire is a wrought nickel-based alloy that contains nickel (Ni), molybdenum (Mo), and chromium (Cr) as its primary elements, with small amounts of tungsten, cobalt, and iron. This alloy has high corrosion resistance against strong acids, including sulfuric, hydrochloric, and hydrofluoric acids, making it ideal for chemical processing, nuclear reactors, and oil and gas applications. Hastelloy C276 offers excellent resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in chloride environments, providing long-term reliability in harsh and critical environments. Its mechanical properties include high strength, hardness, and toughness, making it suitable for valves, pumps, and shafts.


Hastelloy C276 is widely used in aerospace, chemical, petrochemical, pharmaceutical, and oil and gas industries for its high temperature and corrosion resistance properties. In the aerospace industry, the Hastelloy C276 wire is used in critical components such as the combustor liners, afterburner parts, and exhaust ducts of gas turbine engines, which provide resistance to sulfidation and hot gas corrosion. In the chemical industry, the wire is utilized in equipment such as reactors, distillation columns, and heat exchangers, which withstand aggressive chemicals such as phosphoric and sulfuric acids. In the oil and gas industry, Hastelloy C276 is used in downhole tubular, drill collars, and control lines, where it resists corrosion in highly acidic and saline environments.

Welding and Fabrication

Hastelloy C276 wire is easy to weld and fabricate using common welding techniques such as gas tungsten arc welding (GTAW), shielded metal arc welding (SMAW) and gas metal arc welding (GMAW). The wire can be produced in various forms, including round, flat, and square, to cater to different industry’s needs. Hastelloy C-276 wire can be drawn to smaller diameters, making it suitable for intricate parts and applications.


To maintain the corrosion resistance and mechanical properties of Hastelloy C276, the material must be protected from exposure to severe environments that can cause stress corrosion cracking. Regular inspection, cleaning, and maintenance can ensure the longevity and reliability of the components. If the material is exposed to caustic or acidic solutions during operation, it should be rinsed and cleaned after use to prevent damaging levels of corrosion.
