Microstructure and Some Mechanical Properties of AISI 630 Stainless Steel Hardened by Precipitation Hardening

AISI 630 stainless steel hardened by precipitation hardening (PH) is increasingly being used as a maraging steel. In this study, the microstructure and some tensile properties of these steels were examined at room temperature. Additionally, the impact absorption energies of the materials were calculated by conducting the Charpy impact tests on PH steels. This value, calculated as 138.9, is very close to the value obtained by other researchers
