What Does Alloy 625 Mean?

Alloy 625 refers to a Ni-Cr metal mixture that is characterized by its high degree of strength and corrosion resistance. It also possesses significant resistance to elevated temperatures and oxidation.


Corrosionpedia Explains Alloy 625

As an elemental mixture of nickel and chromium, Alloy 625 has excellent malleability properties. This base metal pair alloy provides resistance to a wide range of corrosive environments. Other beneficial characteristics of Alloy 625 include:

  • Increased creep-rupture strength
  • Oxidation resistant up to 1800°F (982°C)
  • Good fatigue resistance
  • Good chloride pitting and crevice corrosion resistance
  • Stress corrosion cracking immunity
  • Flowing and stagnant seawater resistance
  • Fouling impact resistance
