INCOLOY® 925 ALLOY 925 UNS N09925
INCOLOY® 925 ALLOY 925 UNS N09925 nickel alloy is a nickel-iron-chromium alloy with additions of molybdenum, titanium, aluminum and copper suitable for precipitation hardening. It combines high mechanical strength achieved by precipitation hardening with excellent corrosion resistance comparable to that of INCOLOY® alloy 825. Up to about 650°C, INCOLOY® 925 ALLOY 925 UNS nickel alloy N09925 maintains excellent performance, thus making it suitable for high-temperature applications. This alloy has general characteristics of high corrosion resistance, crevice corrosion, and corrosion stress-cracking in many aqueous environments including those containing sulfides and chlorides.
INCOLOY® 925 ALLOY 925 UNS N09925 nickel alloy is used for chemical plant and oil & gas plant components such as valves, pumps, etc.
