This paper studied the effect of quenching media on the mechanical properties of medium carbon steel at particular austenitic temperatures. All the samples except the as-received were heated to the austenitic temperatures of 870 °C, respectively, held for 45 minutes each and quenched in different media i.e. SAE 0 - 40 engine oil, Honey, palm Oil, water and freshly extracted cassava juice. Hardness tests, tensile tests, and microstructural examinations were used to evaluate the quenchants’ effect on the properties of the steel. The results show that the as-quenched samples in oil and honey are fully bainitic structures. Simultaneously, samples quenched in water and cassava juice produced solely martensitic structure because of the sudden temperature change. These structures are unique and were responsible for the improved and favorable mechanical properties so observed.
