Hastelloy C-276 is a safe and extremely durable nickel / molybdenum / chromium alloy developed by Haynes International Inc.
The main components of Hastelloy C-276 are, by percentage:
- Nickel (Ni): 55.25%
- Chromium (Cr): 15.5%
- Molybdenum (Mo): 16%
- Iron (Fe): 5.5%
- Tungsten (W): 3.75%
- Cobalt (Co): 2.5%
- Plus trace elements of copper, manganese, silicon, sulphur, carbon, phosphorus and vanadium
Common Industry Applications
Hastelloy C-276 shows excellent resistance to water based acids, alkalines and salts, so makes a good alternative to 316 Stainless steel for pipes, tubes and fittings. It is commonly used in the oil and gas industry for underwater applications, and for processing chemical waste.
- Water and chemical treatment plants
- Heat exchangers
- Reactor units
- Desulphurisation plants
- Natural gas processing
- Long-lasting and durable
- Unrivalled resistance to seawater
- Excellent corrosion resistance to organic acids, alkalines, salts, sulphuric acid, hydrochloric acid, hydrofluoric acid, phosphoric acid and chlorine
- Acceptable level of corrosion resistance to nitric acid
- Hastelloy C-276 requires expensive raw materials, so is far more costly than other compounds
- The alloy hardens quickly, making machining difficult and further increasing the price. You should expect to pay about nine times as much for a Hastelloy C-276 product as you would for the equivalent in stainless steel
- Tubes - We supply Hastelloy C-276 tubing in 3m lengths, together with a full range of fittings and valves. Tube fittings - available in 25 mm OD.
Alternative Trade Names: Hastelloy C-276 has a number of commonly used trade names, including: Inconel 276, Alloy C276, UNS N10276, Nicrofer 5716
