  • Quenching effect depends upon coolingability of quenchant as well as the composition of steel. Study on the coolingability of quenchants is important in cooling process and heat treatment of steel. Experimental apparatus and measuring method follow Korean Industrial Standard. Distilled water, different concentration of NaCl, NaOH and Na$_{2}$CO$_{3}$ solutions were compared. Also the effect of temperature of distilled water were calculated. Experimental results were examined with F.E.M. analysis.
