The development of electroslag remelting technology (EST) at Special Metals Corporation (SMC) was started in 1968 when the the first laboratory installation built by the Consarc Corporation was installed. This installation had a capability for producing ingots with a maximum diameter of 200 mm by means of electroslag remelting (ESR) and vacuum arc remelting (VAR). The chemical and structural homogeneity, purity, deformability, and forging properties of ESR ingots with a diameter of up to 150 mm are similar to those of VAR ingots. At that time, there was no demand for ESR products in the aerospace industry; VAR was the only appropriate remelting process for producing alloys used for manufacturing rotating components of aircraft engines produced in the United States [1–3].
