Heat Treatment of Steels Metals - Bright Hub Engineering

Heat Treatment Processes.Hardening Hardening involves heating of steel,keeping it at an appropriate temperature until all pearlite is transformed into austenite,and then quenching it rapidly in water or oil.The temperature at which austentizing rapidly takes place depends upon the carbon content in the steelHeat Treatment of Metals 5 Processes MetallurgyThe following are the colours formed on steel in the process of tempering it is called precipitation heat treatment.b.Steel is age-hardened by keeping it at a low temperature for many hours during which the carbon slowly diffuses and renders the steel hard.It is found that if kept at 20 heat treatment process dh40 shipbuilding steel plate#176;C the steel reaches its maximum hardness in Heat Treatment Process-Annealing,Normalizing,Hardening Normalizing is a heat treatment process similar to annealing in which the Steel is heated to about 50 degree Celsius above the upper critical temperature followed by air cooling.This results in a softer state which will be lesser soft than that produced by annealing.
