Product Description

Astm B444 Uns N06625 Inconel 625 Din2.4856 Alloy 625 Steel Tube


Alloy 625 is a nickel-chromium alloy used for its high strength, excellent fabricability and outstanding corrosion resistance. Service temperatures can range from cryogenic to 980°C (1800°F). Alloy 625 strength is derived from the solid solution strengthening effect of molybdenium and niobium on its nickel-chromium matrix.


Thus precipitation-hardening treatments are not required. This combination of elements also is responsible for superior resistance to a wide range of corrosive environments of unusual severity as well as to high-temperature effects such as oxidation and carburization.


Typical Applications

  • Wellhead components
  • Sheathing
  • Downhole equipment for corrosive/ sour service
  • Reactor core
  • Control rod components
  • Gas pipeline control lines
  • Heat exchangers
  • Oil refining
  • Chemical processing
  • Control and instrumentation tubes

Alloy 625 has excellent strength at temperatures up to 816℃. At higher temperatures, its strength is generally lower than that of other solid solution strengthened alloys. Alloy 625 has good oxidation resistance at temperatures up to 980℃ and shows good resistance to aqueous corrosion, but is relatively moderate compared to other more capable corrosion resistant alloys.


Advantages Chemical process industry and sea water application. Alloy 625 is used in short term applications at temperatures up to 816℃. For long term service, it is best restricted to a maximum of 593℃, because long term exposure above 593℃ will result in significant embrittlement.
