An apparatus for quenching a metallic material such as steel is provided. The apparatus includes a heating furnace, a liquid metal sodium chamber, a gas cooling chamber, and a liquid metal sodium removal chamber. The heating furnace heats the metallic material to more than 700° C. The liquid metal sodium chamber includes liquid metal sodium, and the metallic material is cooled approximately to between 100° C. and 250° C. The inert gas chamber includes inert gas such as nitrogen or argon, and the metallic material is cooled approximately to room temperature. In the liquid metal sodium removal chamber, the liquid metal sodium remaining on the metallic materials is removed by using vapor, mist, and water.
