Calculation of Hardenability in High-Carbon Steels^[1]

Hardenability of steel depends on carbon content and other alloying elements as well as on the grain size of the austenite phase. This article provides information on the calculation of high-carbon (carburized) steel hardenability. It contains tables that list multiplying factors that are used for the calculation of case hardenability of carburizing steels and the hardenability of high-carbon steels hardened after a prior normalize or quench treatment. The article reviews the derivation and limitations of multiplying factors.
