Effect of Alloying Elements on the Quench-Crack Sensitivity and Hardness of Induction-Hardened Steels

Abstract

The author investigated the quenching-crack sensitivity and hardenability wliten the notched specimens were induction-hardened. The specimens had been prepared from Mn, Ni, Cr, Ni-Cr, Cr-Mo and Ni-Cr-Mo steels that included various amounts of alloying elements.
From the experimental results, the effect of alloying elements on that characteristics was made clear quantitatively, and an important guide to select the induction-hardening steels was obtained.
