Effect of case depth on fatigue performance of AISI 8620

Feb 01, 1999 · A standard CrNiMo carburizing steel AISI 8620 has been used in the study, and the chemical composition of the steel is given in Table 1.The 25 mm diameter steel bar was received in the hot rolled condition and rotating bending fatigue test specimens were machined as shown in Fig. 1.The surface of the reduced section was mechanically polished using alumina slurry to an average Effects of carburization and hydrogenation on the impact Jul 01, 1995 · Microstructure of the case of furnace-cooled carburized AISI 4118 steel. network (Fig. 2), and that in the inner part is the same as the uncarburized structure (ferrite and pearlite) shown in Fig. 1(b). Typical microstructures of the quenched and tempered (Q + T) carburized specimens are shown in Figs. 3(a) and (b). Martempering/Marquenching - Hardening and tempering Alloy steels are generally more adaptable to marquenching. In general, any steel part or grade of steel responding to oil quenching can be marquenched to provide similar physical properties. The grades of steel that are commonly marquenched and tempered to full hardness are:90Mn4 / 1.1273 / AISI 1090 42CrMo4 / 1.7225 / AISI 4140
