Why is Inconel 718 so widely used in aerospace and high-pressure equipment?

Its age-hardening response gives very high strength while retaining good weldability and fabricability, an unusual combination for a superalloy of this strength class.

Does Sakshi Forge provide Material Test Certificates (MTC) for the Inconel 718 Flange?

Yes, MTC as per EN 10204 3.1 is provided with every dispatch along with PMI test reports.
