Material Notes:
Halcomb 218 is a general purpose hot work tool steel, combining good toughness with moderate high-temperature strength and heat check resistance. Because of its high toughness, it is particularly suited for applications where drastic coolants are used, or where gross cracking resistance is a concern.Information provided by Crucible Industries
