Introduction:

1.Available Shapes: Bar,Rod wire,spring,bolt,fittings

Inconel 725 is highly resistant to corrosion and is age hardenable for extremely high strength. It is used in a broad range of severe corrosive environments. The strength of age-hardened A725 is twice that of A625 annealed. Strength in A725 is obtained by heat treatment and can also be cold worked for even higher strength. There is also a high resistance in reducing and oxidizing environments and increased resistance to pitting and crevice corrosion in sea water and stress corrosion cracking.
