What is Hastelloy C material?

Hastelloy C-22 is a nickel-chromium-molybdenum-tungsten alloy with outstanding resistance to pitting, crevice corrosion and stress-corrosion cracking. The alloy is very resistant to a host of aggressive corrosive media.

Is Hastelloy C the same as C276?

Hastelloy is a representation of a family of corrosion-resistant alloys. Both C-22 and C-276 are from the Hastelloy family, and that similarity can lead to confusion, but C-22 has better overall corrosion resistance compared to C-276 and is often referred as the upgrade from C-276.

What is Hastelloy C used for?

Hastelloy C-276 is one of the oldest, most corrosion-resistant alloys that is still used today. The alloy is primarily made of nickel with molybdenum and chromium additions, and its extremely low silicon content makes it suitable for welding.

What is the difference between Hastelloy B and C?

Hastelloy B is known for its resistance to HCl (hydrogen chloride) and for its creep and rupture strength at temperatures around 1,400°F. Hastelloy C resists active oxidizing agents such as wet CL2 (chlorine), hypochlorite bleach, FeCl3 (iron chloride), and HNO3 (nitric acid).

What is C alloy?

Alloy C. Page 1. Wilfley’s Alloy C is a nickel base alloy that contains significant amounts of molybdenum and chromium. Alloy C has exceptional resistance to strong oxidizing and reducing agents. Classification and Mechanical Properties.

Is Inconel the same as Hastelloy?

Comparing the two alloys, Inconel 625 has a higher chromium content, while Hastelloy C-276 has a higher molybdenum content. This makes them different in corrosion resistance in different environments.

Which is harder Inconel or Hastelloy?

The inclusion of molybdenum makes Hastelloy® harder, stronger at high temperatures, and also makes it great for welding applications. These alloys are easily fabricated and formed. They have good ductility and can be forged and cold worked.
