Graphite electrode is the only material that can withstand high temperatures up to 3000 degrees Celsius without being deformed and melted. So, they are chosen to make steel in electric arc furnaces (EAF) and ladle furnaces (LF).

How does it work in practice? While electrical current passing through the electrode, the electrode tips create an electric arc which generates extremely high heat and melts the steel into molten iron. High temperature resistance and thermal shock resistance makes it an indispensable material for steelmaking.
