Salt bath quenching and tempering is a hardening process that aims at obtaining the required mechanical characteristics in order to bring steel to the required hardness.

Salt bath quenching and tempering can be applied to all types of tool steel, constructional steel, low alloy steel and alloyed steels, whose quenchability is compatible with salt bath quenching. Mainly the process is applied to hot work tool steel and / or to large dies and / or complex shapes.
