Effect of quenching conditions on the formation of the grain structure and the mechanical properties of high-nitrogen austenitic 02Kh20AG14N8MF and 02Kh20AG12N4 steels

Abstract

The formation of the grain structure of high-nitrogen 02Kh20AG14N8MF and 02Kh20AG12N4 steels in forging and quenching and their mechanical properties in this state have been studied. It is found that both steels have close mechanical properties under the same quenching conditions. In 02Kh20AG14N8MF steel, a homogeneous structure of primarily recrystallized austenite grains forms under the quenching conditions under study. In 02Kh20AG12N4 steel, the processes of secondary recrystallization and normal grain growth take place.
