PM M-2

PM M-2 is an improved higher quality tool steel compared to conventional produced M2. The powder metallurgy process results in a homogeneous microstructure exhibiting a uniform distribution of fine carbides with essentially no carbide segregation. It offers improved hardenability and gives better heat treat response in larger tool sections. 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. PM M2’s other general characteristics and physical properties are similar to conventionally produced M2.
