Known for its incredible strength, Incoloy 925 is also corrosion resistant. Standard tuyaux en acier inoxydable et raccords de tuyauterie en acier inoxydable often lack the durability needed in environnements corrosifs, which is not the case with products made with it.
What is Incoloy 925 | UNS N09925
Incoloy 925 is a alliage nickel-chrome-fer that is a modification of Incoloy 825. The alloy is age-hardenable, which means it can achieve very high strengths. It also contains molybdène, copper and titanium, which provide excellent corrosion resistance.

Key Advantages of Incoloy 925
Incoloy 925 achieves ultra-high hardness through a age hardening process. It also resists plastic deformation.
Its composition is resistant to a wide range of corrosive media and resists corrosion par piqûres , corrosion par crevasses et fissuration par corrosion sous contrainte.
Despite its high strength, Incoloy 925 is easy to weld and can form strong, reliable joints, but proper procedures are required.
Incoloy 925 performs well in many industries, including oil and gas, chemical processing and marine. It can be used to handle sour gases and other corrosive media.

Incoloy 925 in High Pressure Piping Systems
- Oil & Gas: Resistant to stress corrosion cracking for downhole tubing, wellhead components and applications in sour gas environments.
- Marine Industry: Resistant to seawater corrosion and pitting corrosion, it is essential for the manufacture of marine fasteners and fittings.
- Chemical Processing: Handles strong acids and chlorides for use in highly corrosive environments.
- High Pressure Systems: Withstands extremely high pressures and is available for shafts, valves and fasteners.
- Piping Systems: Critical stainless steel fittings require extreme strength and corrosion resistance.
Sourcing and Fabricating Inconel 690
A complete Material Test Report (MTR) is required. It verifies the precise composition of the alloy and ensures its performance.
Travailler avec specialized suppliers of stainless steel pipe and fittings. They understand these alloy steels and can ensure proper fabrication and quality control,and are ISO 9001 et CE-PED certified.
This alloy requires specific procedures such as proper traitement thermique is vital. This ensures the integrity of the weld.
It is expensive, so it is important to assess whether the product has a longer service life. This can justify its higher initial cost.
