Annealing involves heating steel to a specified temperature and then cooling at a very slow and controlled rate, whereas tempering involves heating the metal to a precise temperature below the critical point, and is often done in air, vacuum or inert atmospheres.
In tempering, a metal is reheated yet again, but now to a lower temperature than in annealing, normalizing, or quenching. Martensite is not a stable molecule in heat—it is achieved under shock—so tempering steel means destabilizing the martensite to let it start to convert to cementite and ferrite.sp.info What is difference between tempering, annealing ...Annealing: It is the process of heating a metal in a furnace above it's recrystallization temperature and allow it to cool inside the furnace. First the temperature of the material is raised (say 912–915°C for cast iron or steel). Secondly the mat...sp.info What Is the Metallurgical Term Known as Tempering?May 12, 2018 · Tempering is a heat treatment process that is often used to improve hardness, strength, toughness, as well as decrease brittleness in fully hardened steel. A martensitic crystal phase is formed in steel when excess carbon is trapped in the austenitic lath and quickly cooled (usually by water quenching) at a suitable rate.sp.info Quenching, tempering & annealing - Fives in InductionQuenching, Tempering and Annealing: cooling in heat treatment processes. Quenching is when a part that has been heated to a given metal transformation temperature is cooled quickly. Compared to slow cooling, rapid cooling modifies the metal's structure and thereby its hardness characteristics (surface or core) and elasticity.
Tempering. Tempering involves heating steel that has been quenched and hardened for an adequate period of time so that the metal can be equilibrated. The hardness and strength obtained depend upon the temperature at which tempering is carried out. ...

QUENCH & TEMPER. Quenching and tempering is the process that strengthens and hardens materials like steel by subjecting the steel to the extremes of heat past the transformation range and then rapidly cooling (quenching) down the steel. The quenched steel is then returned to the furnace again at a lower temperature to temper the hardness.
