Data on the cooling rate using nano carbon-fluid quenching medium and its effect on the hardness of S45C steel

Nanofluid is a quenching medium that could affect the cooling rate of S45C steel and influence its mechanical properties. This dataset provides the effect of cooling rate using nano-fluid quenchant on the hardness value of S45C steel. The nanofluid consists of 0.1, 0.3, and 0.5 weight percent of nano-sized carbon particles in 100 mL of distilled water. Data on the cooling rate was captured using a temperature data logger linked to the surface of the S45C steel. Data on the hardness value of S45C steel was collected after the quenching process.
