Mechanical property :

• Yield strength: at least 60 ksi

• Tensile strength: at least 120 ksi

• Elongation: at least 30%

Typical application:

• Offshore underwater operation

• aerospace

• Nuclear energy

• Heat exchanger

• Chemical processing

Physical property:

• Alloy625 is an austenitic nickel alloy that resists crevice corrosion and oxidation and is suitable for a wide temperature range from low temperatures to 1800°F. This makes the product ideal for nuclear and aerospace applications. The main feature of Alloy625 is the addition of niobium, which increases the strength of the tube without the need for heat treatment.

Manufacturing characteristics:

• Alloy625 has excellent forming and welding properties, but it is easy to work hard.
