Material Notes:
WR-95 is a modified H10, with cobalt added to improve its high temperature properties. It is an upgrade from H13 in applications requiring improved hot hardness or heat check resistance, at a slight decrease in toughness. It may be used at tool temperatures up to about 1100F, with brief exposures up to about 1200F.Information provided by Crucible Industries
