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 .

However, the timing of heat treatment can vary when using a thread ground ball screw. This is because thread grinding allows the thread to be cut even after heat treating, it is preferred that heat treatment is performed prior to grinding, to ensure that the sizes and lead accuracy will not change due to the heat treatment.
