Hastealloy Specification

Hastelloy is a trademarked name for a group of corrosion-resistant metal alloys primarily composed of nickel, with varying amounts of molybdenum, chromium, cobalt, and iron. These alloys are renowned for their exceptional resistance to harsh environments, including strong oxidizing and reducing agents, making them ideal for chemical processing, marine, and aerospace applications.
