1.Introduction

   Inconel Alloy 625 bar  (UNS designation N06625) is a Ni-Cr based superalloy that possesses

high strength properties and resistance to elevated temperatures. It also demonstrates

remarkable protection against corrosion and oxidation. Its ability to withstand high stress

and a wide range of temperatures, both in and out of water, as well as being able to

resist corrosion while being exposed to highly acidic environments makes it a fitting

choice for nuclear and marine applications.

  Inconel 625 was developed in the 1960s with the purpose of creating a material that

could be used for steam-line piping. Some modifications were made to its original

composition that have enabled it to be even more creep-resistant and weldable.
