O1
: Manganese-chromium-tungsten alloyed steel
A general purpose oil hardening tool steel suitable for back up and punch holder plates. Features of this grade include a good combination of high surface hardness and toughness after hardening and tempering.
AISI O1 is characterized by:
- Good machinability
- Good dimensional stability in hardening
- A good combination of high surface hardness and toughness after hardening and tempering
W1
: The highest quality, water hardening carbon tool steel, controlled for hardenability and subject to the most rigid tests to ensure maximum uniformity in performance, with a composition held to closest limits.
A2
: Chromium-molybdenum-vanadium alloyed steel
Suitable for medium run tooling. This grade features good machinability, high stability after hardening and good wear resistance. AISI A2 can be supplied in various finishes, including the hot-rolled, pre-machined and fine-machined condition. It is also available in the form of hollow bar and rings.
AISI A2 is characterized by:
- Good machinability
- High stability after hardening
- High compressive strength
- Good hardenability
- Good wear resistance
D2
: High-carbon, High-chromium Tool Steel. Virtually non-deforming during heat treatment. High wear resistance, which increases with increasing C and V content.
M2
: 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.
