Inconel® 625 sheets exhibit superior strength and durability and are prized for their outstanding oxidation and corrosion resistance. Maintaining their integrity across a temperature range spanning from cryogenic deep-freezes to 1000 degrees Celsius/2000 degrees Fahrenheit, Inconel® 625 sheets are nickel-based, using columbium and molybdenum as refractory metals. During testing in hostile corrosive conditions, Inconel® 625 displayed near-impenetrable resistance to salt water, neutral salts, fresh water, air and alkaline chemicals.

Thanks to its pressure, heat and corrosion resistance, Inconel® 625 is frequently used in a variety of industries, including:

  • Chemical processing
  • Marine engineering
  • Power generation
  • Aerospace engineering
  • Hardware manufacturing and engineering

Specific applications of Inconel® 625 sheets include furnace hardware, ductwork for gas-powered turbine systems, acid storage and production equipment, production tubing for sour gas, heat shields, chimney liners, heat exchangers, distillation columns and bubble caps.

Inconel® 625 also exhibits strong stability during welding, thanks to the presence of niobium. This super-alloy is also valued for its high levels of fatigue strength and imperviousness to chloride ions. Pickling is achieved by treating the super-alloy with sodium hydride, then submerging it in sulfuric acid for three minutes at a temperature of 74 degrees Celsius/165 degrees Fahrenheit.

Inconel® 625 super alloys are also available in platebarforgings and tubing.
