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.
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
H13
: High hardenability, excellent wear resistance and hot toughness. H13 has good thermal shock resistance and will tolerate some water cooling in service. Nitriding will improve hardness, but can diminish shock resistance if hardened layer is too thick. Electroslag Remelted (ESR) H13 has greater homogeneity and an exceptionally fine structure, resulting in improved machinability, polishability and high temperature tensile strength.
Applications: hot work applications: pressure die casting tools, extrusion tools, forging dies, hot shear blades, stamping dies, plastic molds. ESR H13 is great for aluminum die-casting tools and plastic mold tools requiring a very high polish.
Weldability: Pre and Post-heating recommended, can be welded with oxy-acetylene, inert shielded gas and shielded metal arc; Filler should be similar to the base metal.
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.
M42
: M-42 alloy is a powder metal super-high-speed steel possessing a hardness capability of Rockwell C 68/70. This alloy has been used for cutting tools in the toughest machining operations. The advantages of M42 premium high speed steels include ease of grinding, response to heat treatment, more uniform structure, greater wear resistance and improved toughness.
Applications: Twist drills, Turning tools, End mills, Milling cutters, Broaches, Router Bits, Form tools, Keyway cutters, Dovetail tools, Flycutters, Thread rolling dies, Tool bits
O6
: General purpose, oil-hardening, nondeforming alloy tool steel suitable for applications where extreme dimensional accuracy is required. Applications include ring and plug gages, drawing dies, perforating dies and punches where excellent wear resistance is desired. Contains free graphite in the microstructure to improve machinability.
P20
: Chromium-nickel-molybdenum alloyed steel
A pre-hardened Ni-Cr-Mo-steel supplied at 290-341 HB suitable for die casting of zinc, lead and tin. Also suitable for high strength holder blocks.
Impax Supreme offers the following benefits:
- No hardening risks
- No hardening costs
- Time saving, e.g. no waiting for heat treatment
- Lower tool cost
- Modifications easily carried out
- Can be subsequently nitrated to increase surface wear resistance or locally flame hardened to reduce surface damage
S5
: TLS S5 Shock-Resisting tool steel is a silicon-manganese tool steel which exhibits the highest impact toughness among all of the "S" type steels. The high toughness and the ability to be hardened to 62 Rockwell C make TLS S5 an excellent choice for applications which require higher strength than S7 shock-resisting tool steel. The steel is typically hardened using an oil quench, but for simple geometries, the steel may be water quenched. Typical applications include pneumatic tools, shear blades, mandrels, heavy-duty punches, and stamping dies.
