Crucible Steel WR-95 Tool Steel, AISI H10 Modified
Categories: Metal; Ferrous Metal; Tool Steel

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.
