BÖHLER L925

BÖHLER L925 (UNS N09925) is an age-hardenable nickel-iron-chromium alloy with additions of molybdenum, copper, titanium and aluminium and is designed for high strength and excellent corrosion resistance. The nickel content provides protection against chloride-ion stress corrosion cracking and, in combination with molybdenum and copper, also offers excellent resistance to reducing chemicals. Molybdenum aids resistance to pitting and crevice corrosion. The chromium content of the alloy ensures resistance in oxidising environments.
The alloy exhibits a high degree of corrosion resistance in H2S and CO2 environments and is particularly suitable for sour (H2S-containing) crude oil, natural gas, sulphuric acid, phosphoric acid and seawater. BÖHLER L925 offers high strength and maintains this strength even at high temperatures. BÖHLER L925 meets the requirements of NACE MR0175 and API 6A CRA for acidic applications and can be used for pressure-maintaining and pressure-controlling equipment in corrosive environments. Typical applications include packers, safety valves, pumps, hangers, connectors, fasteners and numerous downhole and surface applications.
