What is Hastelloy?
Hastelloy is a family of corrosion-resistant metal alloys primarily composed of nickel, with varying amounts of molybdenum, iron, cobalt, and chromium. Known for their excellent resistance to strong oxidizers and reducing agents, Hastelloy alloys are ideal for extreme environments.
Popular grades used in flanges include:
- Hastelloy C22
- Hastelloy C276
