The tempering process is an essential stage in heat treatment, especially in very fast cooling, as it brings back ductility. Before we can start the quenching process we need to heat the steel to a high heat.See all results for this questionsp.info Which is the best steel for quenching and tempering?Only steels with a carbon content of approx. 0.3 % or more are economically suitable for quenching and tempering! The decisive criterion for martensite formation is the obstruction of carbon diffusion during the γ - α -transformation. This is achieved by high cooling rates.See all results for this question

The first step to quenching and tempering is austentizing. Austentizing is the process of heating a metal above a critical temperature (typically at least 1350 oF) for sufficient time to transform the microstructure to ...sp.info Quenching and tempering of steel - tec-scienceIn order to influence the hardness and the strength of a steel, a special heat treatment, called quenching and tempering, has been developed. Quensching and tempering can be divided into three basic steps: 1. austenitizing→ heating to above the GSK line into the austenite region 2. quenching → rapid cooling up below γ-α-transformation 3. tempering→ re-heating to moderate temperatures with slow cooling Depending on whether a high hardness (“hardening”) or strength/toughness (“strengthenin…See more on tec-science.com

Finally, heat treat it at a lower temperature for 30 minutes to several hours depending on its size.
Low heat tempering from 50 to 250 degrees Celsius removes the mechanical stresses that exist inside the metal. Also, the metal becomes very elastic and that’s why it becomes wear-resistant in quenching. Medium heat tempering is from 350 to 500 degrees Celsius. In this case, the metal is boosted in both strength and elasticity.sp.info 7 Causes of Quench Cracking in Steel | Production Machining Improper quenchant.
