About Alloy 725
What is Alloy 725?
Alloy 725 also referred to as the UNS N07725 alloy.
It is a nickelchromium-molybdenum-niobium alloy that is highly resistant to corrosion and is age hardenable for extremely high strength.
It has essentially the same corrosion resistance as alloy 625, which is widely used in a broad range of severely corrosive environments.
The strength of age-hardened alloy 725 is of the order of twice that of annealed alloy 625. Because the strength of alloy 725 is developed by heat treatment, not by cold work, ductility and toughness remain high.
It is also used for hangers, landing nipples and high strength fasteners in marine applications.
Alloy 725 is available as pipe, tube, sheet, strip, plate, round bar, flat bar, forging stock, hexagon, wire and extruded section.
