Alloy 925

Alloy 925 is an age-hardenable nickel-iron- chromium alloy that combines good high strength properties and excellent corrosion resistance. The addition of molybdenum and copper gives the alloy resistance to reducing chemicals, and to pitting and crevice corrosion. The combination of Nickel and Chromium provides protection in both oxidizing and reducing atmospheres.

The high Nickel content also gives resistance to chloride ion stress-corrosion cracking, pitting and crevice corrosion resistance is also
excellent. This alloy is often chosen for liquid and gaseous applications where a combination of high strength and corrosion resistance is required. Alloy 925 demonstrates excellent resistance to corrosion cracking caused by hydrogen sulfide in sour gas applications. Applications include down-hole and above ground components.
