What is Hastelloy c276 tube ?

Alloy C276 has nickel, chromium and molybdenum in its chemical composition with added tungsten. It shows excellent corrosion resistance in various environments. The Hastelloy C276 tube also shows pitting and crevice corrosion resistance. They have a low carbon content which minimizes the risk of carbon precipitation during welding. The EN 2.4819 square tubing shows good resistance to elevated temperature conditions that can go up to 1038°C.

They possess good mechanical properties, with a minimum yield strength of 345 Mpa. Nickel C276 condenser tubes can achieve strength by undergoing the pilger process. They can also maintain their toughness at cryogenic temperatures. The 2.4819 Hastelloy C276 gas tube can be hot worked within the temperature range of 870-1230 °C. They have a high work hardening rate, so annealing is a recommended process.

What is the difference between Inconel 625 and Hastelloy c276?
  • Inconel 625 has a high chromium content whereas Hastelloy C276 has higher molybdenum content.
  • 625 shows good oxidation resistance whereas UNS 0276 heat exchanger tube material is reduction resistant. Thus, 625 is preferred in oxidizing environments whereas C276 is for reducing solutions.
What are the disadvantages of Hastelloy C276 seamless tube?
  • The disadvantages of Hastelloy C276 seamless tube will include:
  • C276 is a premium alloy and the seamless tube made from this can be very expensive.
  • It has a specialized composition and is subject to limited availability. This can increase the price of the products and the delivery timelines.
  • nickel alloy C276 bright annealed tube has a high work hardening rate and low thermal conductivity. Thus, they are quite challenging to machine and fabricate.
  • C276 material can get brittle above the temperature of 704 °C.
  • They have a high coefficient of thermal expansion.
  • Hastelloy C276 tube suppliers suggest that the material might not be ideal for all corrosive environments. For example, it can exhibit localized corrosion if exposed to high temperature concentrated sulphuric acid.
Can you weld C276 tubing?

C276 tubing can be easily welded and processed using standard procedures. The hot working temperature for the material is within the range of 870-1230 °C. ERNiCrMo-4 or ERNiCrMo-4 can be used as a filler material in welding DIN 2.4819 redrawn tube for chemical and petrochemical industries.
