What material is Incoloy925? What chemical composition?

Incoloy925/alloy925 is an iron-nickel base alloy that can be strengthened by aging. Incoloy925/alloy925 alloy has excellent corrosion resistance to reducing chemical medium and good crevice corrosion resistance due to the composite action of Cr, Mo and Cu in the alloy. The nickel content of this alloy is enough to ensure its resistance to stress corrosion caused by chloride ions, and it is mainly used in fields requiring high strength and corrosion resistance.

Chemical composition of Incoloy925/alloy925: C: ≤ 0.03, Si: ≤ 0.5, Mn: ≤ 1.0, S: ≤ 0.03, Cr: 19.5 ~ 22.5, Ni:42~46, Mo.

Incoloy925/alloy925 corresponding brands: national standard: 0Cr22Ni42Mo3Cu2Ti2AlNb, American standard: Incoloy925/alloy925, No9925.

Corrosion resistance of Incoloy925/alloy925: It shows good overall corrosion resistance, pitting corrosion resistance, crevice corrosion resistance and stress corrosion resistance in both oxidizing and reducing medium environments. Suitable for sour crude oil, H2SO4, H3PO4 and seawater.

Incoloy925/alloy925 and welding: easy hot working, hot working temperature is 870~ 1 175 degrees. In order to obtain the corrosion resistance and strength level after direct aging, the final processing temperature should be controlled at 870~980 degrees. The cold forming behavior is similar to that of 825 alloy, but the work hardening rate is slightly increased. Solution annealing should be at 980~ 1040℃. GTAW and knawincoloy 925/alloy 925 can be used for welding, but submerged arc welding is not recommended. ?

Incoloy925/alloy925 Physical properties: density: 8. 1 g/cm3, melting point: 1343℃, tensile strength: 650Rm N/mm2, yield strength: 295 RP0.2 N/mm2, elongation A5? %:30。

Application in Incoloy925/alloy925 field: it is often used as parts of oil and gas drilling equipment. Its Incoloy925/alloy925 alloy from Jue Yuan is also suitable for fasteners, pump shafts and high-strength piping systems.
