Heating the material above the critical temperature causes carbon and the other elements to go into solid solution. Quenching "freezes" the microstructure, inducing stresses.How Quenching Hardens Steel in MetalworkingAs a result, quenched steel typically undergoes a tempering process. This involves reheating the metal to a temperature below a critical point, then allowing it to cool in the air. Typically, steel will be subsequently tempered in oil, salt, lead baths, or furnaces with air circulated by fans to restore some of the ductility (ability to withstand tensile stress) and toughness lost by conversion to martensite.What is Heat Treatment? Hardening, Tempering, Annealing 45b quenching and tempering steelThe microstructure of a hardened steel part is ferrite, martensite, or cementite. 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.
