- Electro Slag Remelting
ESR or electro slag remelting (also known as electro flux remelting) is a process used for remelting and
refining ofsteel s and specialalloy s which are used for critical applications in aircraft, thermal and nuclear power plants, defence hardware, etc. [citation|title=The Superalloys: Fundamentals and Applications |author= Roger C.

It is a common practice in European industries. ESR reduces other types of inclusions as well, and is seen as an alternative to the vacuum arc remelting method that is prevalent in US industries.
