Inconel is a family of austenitic nickel-chromium-based superalloys. Inconel
alloys are oxidation-corrosion-resistant materials well suited for
service in extreme environments subjected to pressure and heat. When
heated, Inconel forms a thick, stable, passivating oxide layer
protecting the surface from further attack. Inconel retains strength
over a wide temperature range, attractive for high temperature
applications where aluminum and steel would succumb to creep as a result
of thermally induced crystal vacancies. Inconel`s high temperature
strength is developed by solid solution strengthening or precipitation
hardening, depending on the alloy. Inconel
alloys are typically used in high temperature applications. Common
trade names for Inconel Alloy 625 include: Inconel 625, Chronin 625,
Altemp 625, Haynes 625, Nickelvac 625 and Nicrofer 6020
