Therefore, the quench- Because time at temperature is also important, heat treatment can be further defined as a series of time-temperature treat-ments. HEAT TREATMENT:- The process of heat treatment is carried out first by heating the material and then cooling it in the brine, water and oil. Typically, the energy used for process heating accounts for 2% to 15% of the total production cost. Although more expensive and highly complex, heat treatment processes are absolutely essen-tial in most applications and, if sufficiently understood and properly used, definitely are a key step towards producing the op-timum material. These studies highlight the relationships between critical heat treatment process control parameters and heat treatment success. Classical Heat Treatment is an indispensable set of processes within the manufacturing chain of most of the products Heat treatment of ductile cast iron includes stress relief and annealing, as well as heat treatments used for steels including normalize and temper (for higher strength and wear-resistance), quench and temper 1 Background and Objectives Iron is one of the oldest known metals, and carbon is the cheapest and most effective alloying element for hardening iron.

Post weld heat treatment (PWHT) is a controlled process in which a material that has been welded is reheated to a temperature below its lower critical transformation temperature, and then it is held at that temperature for a specified amount of time. A ferrous metal has iron as its main element. Annealing, Normalizing, Quench Hardening, Tempering, and Austempering are five of the important heat treatments The purpose of heat treatment is to soften the metal, to change the grain size, to modify the structure of the material and to relieve the stress set up in the material after hot and cold working. An intermediate hold at 595° C is recommended for those weldments to relieve residual stresses and to reduce the susecptibity to cracking during post weld heat treatment. Heat treatment is a method used to alter the physical and sometimes chemical properties of a material. Unit 5Heat Treatment 11 Heat treating is a group of industrial and metalworking processes used to alter the physical, and sometimes chemical, properties of a material.
