Alloy 625 and Inconel 625 are the same material.
Alloy 625 and Inconel 625 are actually the same material, just with different names.
Alloy 625, also known as Inconel 625 or Inconel 625, is a nickel-based high-temperature alloy composed mainly of nickel, chromium and molybdenum, and also contains small amounts of elements such as iron, niobium and copper. This alloy performs well in high temperature and corrosive environments, with characteristics such as high strength, oxidation resistance, water corrosion resistance and excellent weldability.
