Average quench rates are useful to compare experimental results from various quench methods. However, average quench rates only compare results in a "critical" temperature range, where precipitation is most likely to occur. This method is not entirely accurate because significant precipitation can also occur outside the specified critical temperature range of average quench rates. In addition, for plain carbon steel or high-strength alloys, toughness and corrosion resistance could be impaired without significant loss of tensile strength. In this paper a more sophisticated comparison called quench-variable analysis is used to quantitatively predict the property or optimize the property of plain carbon steel. The paper studies the relative influence of austenizing temperature, quenching media, soaking time, size and shape of materials, and surface condition on the fracture response of plain carbon steel.
