Lork Group high-quality Incoloy 925 (UNS N09925) is an age-hardenable nickel-iron-chromium alloy with the addition of molybdenum, copper, titanium, and aluminium.

Lork Group high-quality Incoloy 925 (UNS N09925) is an age-hardenable nickel-iron-chromium alloy with the addition of molybdenum, copper, titanium, and aluminium. Each of these additions plays its own part in making Alloy 925 a high-strength alloy with excellent corrosion resistance.

Incoloy 925 has excellent corrosion resistance consistent with Alloy 825. High levels of nickel ensure protection against stress corrosion cracking, whilst the additional molybdenum and copper resist reducing environments, in the same way that Chromium resists oxidising environments. Molybdenum enhances resistance to pitting and crevice corrosion, lifting the Pitting Resistance Equivalent number (PREN) to above 26.

With such a balanced composition, Alloy 925 is particularly suited to down-hole applications in sour gas wells, but can also be used in less aggressive applications as it resists general, pitting, crevice and stress corrosion cracking in most aqueous environments where chloride or sulphide ions may be present.
