In the current paper, the main purpose of carbon steel quenching was reviewed by different cooling media for a set of researches, where will be mentioned to the change that happen of the metal in order to obtain new properties according to the required applications. The water and oil were used as the two main media of quenching most often to obtain rapid quenching after heating to austenitic temperature in most studies, but two these media were used in various forms such as the use of salt solution or cooled and hot water in addition to that can used engines oil, vegetable oil, various polymeric fluids and others. From previous studies and types of quenching media mentioned in this review, some of mechanical properties such as hardness and tensile strength improved when using water rather than oils while toughness property increase at cooling in polymer fluid. However, the goal of quenching were obtained an increase in the value of hardness, impact strength, tensile strength, wear resistance and improved other required properties according to the certain manufacturability and industry requirements.
