In demanding industrial environments, Incoloy 825 Ligas holds strategic importance.Conventional tubos de aço inoxidável e conexões para tubos de aço inoxidável often prove inadequate in such conditions. Incoloy 825 provides an exceptional solution for severe ambientes corrosivos.
What is Incoloy 825 Alloy | UNS N08825
Incoloy 825 is a liga de níquel-ferro-cromo. It is a highly engineered material. Its composition includes molibdênio, copper, and titanium. This unique combination gives it incredible power. It can resist both oxidizing and reducing acids. Its stabilized composition also makes it resistant to corrosão pós-soldagem.
Key Performance Advantages of Incoloy 825 Alloy
Incoloy 825 alloy is specifically engineered to withstand diverse chemical environments, delivering exceptional performance in both oxidizing and reducing acid conditions.
The alloy’s high nickel content provides robust resistance to rachaduras por corrosão sob tensão, particularly critical in chlorine-rich environments, effectively preventing catastrophic failure under stress.
A stable composition ensures material integrity post-welding, effectively resisting sensitization and guaranteeing welded joints maintain full corrosion resistance.
The presence of molybdenum and cromo elements enables resistance to corrosão por pite e corrosão em fendas, protecting material integrity in stagnant areas—critical for pipe fittings and flanges.

- Piping Systems: For critical stainless steel pipe fittings, Incoloy 825 provides extreme corrosion resistance. It keeps your system working perfectly.
Sourcing and Fabricating Incoloy 825 Alloy
Always ask for a Material Test Report (MTR). This proves the material is what it should be.
Trabalhar com 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 e CE-PED certified.
This alloy needs specific welding methods. Make sure your team knows how to handle it.
It’s more expensive upfront. But it lasts much longer. This saves you money in the long run.
