Tool Holders

The newly developed, patent pending, BÖHLER E185 AMPO is an AM powder, fulfilling the highest demands from various industries, ranging from motorsport to engineering components and any kind of prototype applications. This low alloyed steel with easy printability and the possibility for surface treatments (e.g. case hardening or nitriding) was developed especially for the demands of the 3D printing industry. The material shows an excellent combination of strength and toughness.

BÖHLER K305 belongs to the group of 5% chromium steels and corresponds to the material 1.2363 (X100CrMoV5, A2). Compared to conventional tool steels with 1% carbon and low chromium content, BÖHLER K305 has significantly better through hardenability and wear resistance. This class of 5% chromium steels is used in situations where grades like 1.2842 are no longer sufficient in terms of wear resistance and through hardenability but materials like 1.2379 are not yet required. BÖHLER K305 is used for punching and cutting tools, die plates and inserts, thread cutting tools and machine knives in the wood, paper and recycling industries.

BÖHLER K460 corresponds to the material 1.2510 (100MnCrW4, O1) and has comparable properties to the popular tool steel 1.2842. Additional alloying with tungsten achieves higher resistance to abrasive wear compared to the tool steel 1.2842. BÖHLER K460 offers the advantage of simple heat treatment with low hardening temperatures and single tempering. However, this characteristic tempering behaviour limits the use of advanced coatings. The material has a good hardening response, but only moderate through hardenability. BÖHLER K460 is used for punching and cutting tools, plastic molds, thread cutting tools and machine knives in the wood, paper and recycling industries.

BÖHLER K605 is approximately equivalent to the material 1.2721 (~50NiCr13). The alloy concept of this tool steel is similar to the one of 1.2767. With its high nickel content, this material offers a very good combination of through hardenability and toughness. The higher carbon content compared to material 1.2721 results in a better hardening response and consequently higher compressive strength. The material is used in applications such as forming, bending and embossing tools.

BÖHLER M200 is a prehardened, non-corrosion-resistant chromium-manganese-molybdenum alloyed plastic mould steel with very good machinability and uniform strength over the entire cross-section of medium-sized dimensions.

BÖHLER M238 is a prehardened, non-corrosion-resistant plastic mould steel with good machinability. The addition of Ni guarantees uniform strength across the entire cross-section, even with large dimensions (up to 600 mm).

BÖHLER M238HH corresponds to BÖHLER M238 in High-Hard product variant. A variation in the heat treatment enables significantly higher wear resistance and edge-stability for improved tool life.

BÖHLER M261 is a precipitation-hardenable steel for plastic molds that exhibits very good machinability in the as-delivered condition – solution-annealed and aged. Compared to 1.2312, BÖHLER M261 has a higher resistance to pressure and wear. By eliminating the need for additional heat treatment, the throughput time can also be significantly reduced.

BÖHLER M315 is a prehardened, corrosion-resistant martensitic plastic mold steel. Due to its chemical composition, BÖHLER M315 has improved machinability compared to 1.2085 and is approved for food contact.

BÖHLER M789 AMPO is a newly developed maraging steel, which combines the mechanical properties of 1.2709 with the corrosion resistance of 17-4PH. This patent bending grade can easily printed without any preheating and achieves a hardness of about 52 HRC with a very easy heat treatment. Furthermore, this material shows an excellent polishability, which makes it the ideal choice for inserts with conformal cooling in plastic injection molding and in any other application where a high hardness and corrosion resistance is of need.

BÖHLER W300 ISOBLOC is a 5% chromium steel and corresponds to material number 1.2343 (X37CrMoV5-1).

The combination of these properties makes it a top performer in high- and low-pressure die casting as well as in closed-die and open-die forging. In addition, this material has very good polishability and is therefore also often used as a molding material for plastic injection molds.

BÖHLER W300 ISODISC is a 5% chromium steel and corresponds to material number 1.2343 (X37CrMoV5-1). This common tool steel has good hot toughness as well as a high hot hardness and a high resistance against heat-checkings. The combination of these properties makes it a standard choice in extrusion, forging and low-pressure die casting. This material is also available as W300 ISOBLOC which is a remelted grade with improved cleanliness, homogeneity and toughness.

BÖHLER W302 ISOBLOC is a 5% chromium steel and corresponds to material number 1.2344 (X40CrMoV5-1). Produced via the electroslag remelting process (ESR), this tool steel has very high hot toughness as well as very high hot hardness and a very good resistance against heat-checkings. The combination of these properties makes it a top performer in closed- and open-die forging as well as in high- and low-pressure die casting. In addition, this material has very good polishability and is therefore also often used as a molding material for plastic injection molds.
