This paper deals with the predictive equation for obtaining a maximum hardness in the heat-affectedzone. The estimating equation was derived using the kinetics of phase transformation and the theory of heat transfer. The material constants included in the equation were determined from hardness data of CCT-diagram by the stepwise multiple regression analyses. The predictive equation was proved to be more reliable than other formulae by comparing with data of hardness reported by many researchers.
