Inconel alloy 718SPF, like alloy 718, has excellent resistance to corrosion in many media. This characteristic, similar to that of other nickel-chromium alloys, is a function of its composition.
Inconel 718SPF （UNS N07719） was developed to meet the need for a nickel-base alloy suitable for manufacture into complex shaped components subject to a combination of high temperature, high temperature corrosion and high stress. Inconel alloy 718SPF meets all the mechanical property requirements of AMS 5596G, as annealed plus aged, as well as all requirements of AMS 5950, which is specific to INCONEL alloy 718SPF.
Inconel 718SPF alloy is a specifically"tailored"version of INCONEL alloy 718, designed for the superplastic forming process. The alloy is optimized for the process by rigorous control of composition, melt practice and rolling conditions.
Superplastic forming, now highly sophisticated and used extensively for producing commercial and military aircraft components, is an ideal process for manufacturing complex shaped parts. Use of superplastic forming can enhance component performance and reliability while lowering overall manufacturing cost by reducing the need for extensive welding or other joining methods, lowering the inventory of parts and simplifying the manufacturing process.
