In the present research, resistances to melt-out and heat checking of surface modified H13 hot die steels, such as gas nitriding(GN) and micro-blasting(MB), were investigated.
WebFigure 1: Hot work die steel showing severe heat checking. In the conventional hot work steels, the groups are divided into three, depending on the principal elements utilized for red hardness: thus the steels are classed as chromium, tungsten or molybdenum types. Table 1 shows the nominal composition being listed under AISI H series. WebThe Jominy end-quench test utilizes a 100 mm (4 inch) long by 25 mm (1 inch) diameter round bar of the steel of interest (see Figure 15(a)) is first normalized to eliminate any differences in microstructure due to previous hot working (147).After normalizing, the test bar is heated to the specified austenitizing temperature. The austenitizing temperature is …
