Review and cite water quality analysis protocol, troubleshooting and other methodology information | contact experts in water quality analysis to get answers, water conditioning counteracts the hardness in water to prevent a build up of limescale. it differs from water softening in that softening removes minerals from the water, whereas conditioning .... Tempering (metallurgy) - wikipedia. tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys.tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air.
