Inconel 625 Oxidation Resistance

Inconel 625 oxidation resistance is higher than that of other alloys. It is one of the many reasons that this alloy is purchased so commonly within the industries of chemical process and aerospace.

Oxidation is reliant mainly on the oxygen level of the atmosphere, with gases such as carbon dioxide and steam supporting the reaction.

Other properties of alloy 625 include resistance to pitting, crevice corrosion and resistance to nonoxidizing atmospheres, thanks to the added Nickel and molybdenum present within the material.

Inconel 625 Oxidation Resistance Charts

Comparative burner rig oxidation resistance tests at 1000 Hours were carried out by Haynes International. Samples included 9mm x 64mm x thickness) in a rotating holder with x2 types of fuel oils.

Burned at a ratio of air to fuel 50:1 for 1000 hours of testing. Please note: Samples used were removed from the gas stream every 30 minutes, in which they would be fan cooled to a ambient temperature – allowing reinsertion into the tunnel.

Applications of Inconel 625

  • Marine Industry
  • Subsea applications such as submarine fittings
  • Aerospace and Jet Engines
  • Chemical and Food processing equipment
  • Filtration and waste water disposal or tanks

In mild environments: For fresh and seawater applications with neutral salts and alkaline media there is almost no attack present with use of alloy 625.

In severe environments: In corrosive environments that are challenging to other alloys, Inconel 625 is able to supply resistance to oxidising chemicals because of the combination of nickel and chromium within the metal.

High nickel concentration and molybdenum provides high resistance to non-oxidising environments.

The Ultimate Solution For Corrosive Environments

Our highly corrosion resistant Inconel 625 fittings and valves are manufactured in the UK and exported worldwide.
