Inconel 718SPF Chemical Composition
Inconel 718SPF Material Properties Overview
As a leading supplier and manufacturer in China, Arialloy supplies cost effective inconel 718SPF products for engineering and procurement.
Inconel 718SPF (UNS N07718 / W.Nr. 2.4668) is a precipitation hardenable nickel chromium iron superalloy containing niobium, molybdenum, titanium, and aluminum. It combines the corrosion resistance, high strength, and weldability of inconel 718 with a fine grained structure suited to superplastic forming. The fine grain condition is produced through controlled cold rolling and annealing, while reduced carbon and niobium limits help minimize carbide precipitation during forming.
In the mill annealed condition, the material offers high ductility, stable grain structure, and low forming stress at controlled strain rates. At approximately 954°C (1750°F), it can achieve substantial elongation while maintaining a controlled microstructure. The material is normally supplied as thin annealed sheet, and SAE AMS 5950 defines key requirements for the 718SPF grade. After forming, solution treatment and aging can develop gamma prime and gamma double prime precipitates for high tensile, creep, and rupture strength. Compared with conventional inconel 718 sheet, its controlled fine grain structure improves superplastic formability and retains useful tensile properties when forming is controlled.
Arialloy supports grade confirmation, sheet thickness and width selection, heat treatment, dimensional requirements, inspection, material test reports, and shipment documentation.
Inconel 718SPF Corrosion Resistance
Inconel 718SPF retains corrosion resistance of inconel 718 across many aqueous and chemical media. Nickel supports resistance in a range of inorganic and organic environments and helps resist chloride ion stress corrosion cracking.
Chromium improves resistance to oxidizing media and sulfur compounds, while molybdenum contributes to resistance against localized attack such as pitting. The annealed condition supports consistent behavior, but corrosion performance depends on heat treatment, surface condition, welding, exposure temperature, acidity, chloride concentration, and stress.
Inconel 718SPF Mechanical Properties
In the annealed condition, inconel 718SPF combines high tensile strength with ductility for superplastic forming. Representative data show a 0.2 percent yield strength of 852 MPa, tensile strength of 1121 MPa, and elongation of about 29 percent, with ASTM grain size near No. 13. After aging, yield strength can reach 1461 MPa and tensile strength about 1586 MPa, while elongation is about 14 percent.
Inconel 718SPF Temperature Characteristics
Inconel 718SPF is processed for superplastic forming at approximately 954°C (1750°F), where its controlled fine grain structure provides high strain capability and grain stability during the forming cycle.
After forming and aging, the alloy offers strong creep and stress rupture resistance at elevated temperature, with inconel 718 generally retaining useful strength to about 700°C (1300°F). Performance depends on heat treatment, grain growth, exposure time, applied stress, and atmosphere.
