Unlike ordinary carbon steel, high manganese steel after quenching in the water is not hardened, but become soft, so high manganese steel heat treatment is also called water toughness treatment. In the heat treatment process, the carbide is dissolved in the solid state to the austenite to go, so called solid solution strengthening treatment.

Tempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the alloy. The reduction in hardness is usually accompanied by an increase in ductility, thereby decreasing the brittleness of the metal. Tempering is usually performed after quenching, which is rapid cooling of the metal to put it in its
