Materials Science Aims and scope

Abstract

We investigate impact-cyclic and impact-abrasive stabilities of commercial carburized 20KhN3A steel and the new low-alloyed 20KhGNBTChA steel and establish that the impact-cyclic stability of the new steel is greater than that of commercial 20KhN3A steel by a factor of 1.5–2. Tests of impact-abrasive stability confirm the advantages of the new steel, which enables us to recommend this steel for the production of rock-crushing tools.
