Hastelloy C22 spring wire is a premium nickel-based alloy designed for the most aggressive and unpredictable environments. Known for its exceptional balance of resistance to oxidizing and reducing agents, Hastelloy C22 is particularly valued in industries where conventional alloys quickly fail. The presence of chromium, molybdenum, and tungsten in its composition allows it to resist pitting, crevice corrosion, and stress-corrosion cracking even in chloride-laden or acidic conditions.
At DLX, we supply Hastelloy C22 spring wire that meets strict global standards such as ASTM B574, DIN 2.4602, and EN specifications. This ensures our spring wire not only matches but often exceeds the demands of clients across chemical, marine, and environmental sectors.

The growing complexity of industrial operations has led to higher demands for advanced materials that can resist multiple forms of corrosion at once. Chemical plants, desalination systems, and pharmaceutical facilities increasingly operate in environments that combine oxidizing and reducing chemicals—conditions where many alloys fail prematurely. Hastelloy C22 has emerged as a solution due to its versatility and reliability.
While stainless steel and even other nickel alloys provide partial resistance, Hastelloy C22 stands out by offering stability against both oxidizing and reducing media. This dual resistance gives companies a long-term cost advantage, reducing downtime, replacement frequency, and maintenance costs.
Applications
Hastelloy C22 spring wire has become an industry standard for critical applications, including:
- Chemical processing: Springs in pumps, mixers, and valves exposed to mixed acids, chlorine, and organic solvents.
- Marine & offshore: Springs in desalination units, offshore rigs, and shipboard systems requiring long service life in saltwater.
- Pharmaceutical & biotech: Springs in equipment where both chemical resistance and material purity are essential.
- Pollution control systems: Used in scrubbers, waste treatment, and flue gas cleaning.
- Energy sector: Ideal for nuclear and geothermal systems facing extreme chemical exposure.
