Other common name: Alloy 925,UNS N09925
INCOLOY® alloy 925 is a high-strength, corrosion-resistant austenitic nickel-iron-chromium alloy. By adding titanium and aluminum, the entire alloy matrix forms Ni 3 (Al, Ti) γ ('ϒ') elemental precipitates (alloy K500). , Alloys 718 and 725 have similar principles), precipitation hardening in the aging process to obtain high strength. In addition, the combination of molybdenum, copper, nickel, molybdenum, copper and other elements added to the alloy enhances the alloy's resistance to reducing environments. Sufficient nickel content can effectively prevent chloride ion stress corrosion cracking, and molybdenum increases the alloy’s resistance Pitting corrosion and resistance to crevice corrosion, chromium improves the oxidation resistance of the alloy. Alloy 925 can resist sulfide stress cracking and stress corrosion in "sour" crude oil and natural gas environments, so it is widely used in downhole and surface gas well components, including tubular products, valves, tool joints and packers.
● Good machinability under solution treatment and aging conditions
● Corrosion resistance in oxidizing and reducing environments
● Good stress corrosion and stress cracking performance in chloride
● Excellent resistance to pitting and crevice corrosion
● Outstanding corrosion resistance under acidic conditions, suitable for downhole crude oil and natural gas wells, etc.
