Material Notes:
REX M2S (1.0C) is a sulfur-bearing high carbon version of the regular CRUCIBLE REX M2 high speed steel. The sulfur addition provides good grindability and an improvement in machinability of 25 to 35 percent over a comparable nonsulfurized grade. The increase in carbon content produces higher attainable hardness, increased wear resistance and red hardness which contribute to significant gains in cutting tool performance. The higher carbon offers improved hardenability in larger tool sections.Information provided by Crucible Industries
