Outstanding LPC case hardening of Pyrowear® Alloy 53

For quenching, the process was run not only at the reference temperature of 910'C (1675°F) but also at higher (955 C/1750T) and lower (870 C/1600'F) temperatures. The graph in Fig. 6 shows the hardness profiles, which indicate that quenching temperature has the greatest effect on the core...

Description
Summary:For quenching, the process was run not only at the reference temperature of 910'C (1675°F) but also at higher (955 C/1750T) and lower (870 C/1600'F) temperatures. The graph in Fig. 6 shows the hardness profiles, which indicate that quenching temperature has the greatest effect on the core hardness. It increases with temperature to 37, 41 and 43 HRC and results from the higher solubility of carbides and higher saturation of austenite with carbon at higher temperatures.
