Alloy
HX, also known as Hastelloy® X or Inconel® HX, is a nickel-based superalloy
with exceptional high-temperature strength and oxidation resistance. It is
designed to withstand extreme environments and is commonly used in gas turbine
engine components, aerospace applications, and high-temperature structural
applications.
One of the key features of Alloy HX is its exceptional resistance to
high-temperature oxidation, corrosion, and carburization. It can withstand
aggressive environments, including sulfuric acid, nitric acid, hydrochloric
acid, saltwater, and oxidizing/ reducing conditions. This corrosion resistance
makes it suitable for applications exposed to harsh chemical and
high-temperature environments.
The alloy finds extensive applications in gas turbine engine components, aerospace applications such as afterburners and jet engine tailpipes, as well as chemical processing equipment, and nuclear industry systems.
