Crucible CPM Rex 54 HS is a cobalt-bearing high speed tool steel that is produced by the proprietary Crucible Particle Metallurgy (CPM) process. It combines the wear properties of the popular high vanadium M4 grade with the red hardness of the cobalt-bearing M35/Crucible CPM Rex 45 HS grades. Crucible CPM Rex 54 HS may be used as an upgrade for improved red hardness over M3 or M4 without giving up the abrasion resistance, or as an upgrade for improved wear resistance over M35 or Crucible CPM Rex 45 HS without giving up the red hardness. This datasheet provides information on composition, physical properties, microstructure, hardness, and elasticity. It also includes information on wear resistance as well as heat treating and surface treatment. Filing Code: TS-818. Producer or source: Crucible Industries LLC.
