| PM M2 is an improved quality tool steel compared to conventionally produced material. The powder metallurgy process results in a homogeneous microstructure exhibiting a uniform distribution of fine carbides with essentially no carbide segregation. PM M2 tools will have a finer grain size, much better toughness, and superior grindability in the heat treated condition compared to those made from conventional M2. The higher carbon content (1.00% vs. 0.85%) of PM M2 permits higher attainable hardness. It also offers improved hardenability and gives better heat treat response in larger tool sections. PM M2’s other general characteristics and physical properties are similar to conventionally produced M2. Information provided by Crucible Specialty Metals. |
