Complex Cut

BÖHLER K245 corresponds to the material 1.2101 (62SiMnCr4). This cold work tool steel is essentially a spring steel optimized for cold work, with very good toughness and spring properties. BÖHLER K245 offers the advantage of simple heat treatment with very low hardening temperatures and single tempering. However, this characteristic tempering behaviour limits the use of advanced coatings. BÖHLER K245 is especially suitable for thin-walled tools such as screwdrivers, hole punches, center punches, ejector pins, punches and cutting tools.

BÖHLER K340 ECOSTAR belongs to the group of conventionally produced 8% chromium steels. Compared to conventional 12% chromium steels, this conventionally smelted tool steel has better toughness, hardening response and higher adhesive wear resistance. This combination of high adhesive wear resistance and toughness also offers advantages for industrial knives subject to high stress. This grade is also used for stamping and cutting tools.

BÖHLER K340 ISODUR belongs to the group of 8% chromium steels. This tool steel is produced using the electro-slag remelting (ESR) process developed by BÖHLER. This re-melting technology ensures the lowest micro and macro segregation as well as excellent purity and uniformity of the material. Compared to conventional 12% chromium steels, BÖHLER K340 ISODUR offers significantly better toughness, hardening response and higher resistance to adhesive wear. This material is therefore used in virtually all cold work applications in situations where tool steels like 1.2379 are insufficient in terms of adhesive wear resistance and toughness. K340 ISODUR also features better machinability and reduces the risk of stress cracking during electrical discharge machining.

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 W403 VMR is a vacuum remelted material which was developed as a problem solver for tools for where a standard solution is no longer sufficient. The steel can be assigned to the 5% chromium steels and has a very high purity due to the special manufacturing technology. In addition, the increased molybdenum content leads to improved thermal resistance as well as wear resistance, which makes BÖHLER W403 VMR an all-rounder that is often used for highly stressed dies in the die casting sector. In addition, Böhler W403 VMR has outstanding polishability. For this reason, the steel is also popular as a molding material for plastic injection molds.

Uddeholm Calmax is a medium alloyed tool steel suitable for short and medium run tooling in applications where a very high chipping resistance is required. The property profile makes Uddeholm Calmax a robust cold work tool steel for heavy duty blanking and forming. Benefits Uddeholm Calmax is very useful for severe cold work applications where there are very high demands on chipping resistance Reduced maintenance and downtime costs combined with increased productivity due to the reduced likelihood of premature failures. Reduced maintenance and downtime costs combined with increased productivity due to simplified maintenance procedures Good weldability and the availability of welding electrodes with the same chemical composition as Uddeholm Calmax Good flame-, induction- and laser hardenability Standard specification W.nr 1.2379 / AISI D2 / AFNOR 60CMDV 18

Uddeholm Mirrax ESR is a through hardening corrosion resistant steel with very good polishability. Mainly intended for medium to large cross sections. It has a unique combination of toughness, corrosion resistance and through hardening properties. Benefits Low mould maintenance costs: The surface of cavity impressions retain their original finish over extended running periods. Moulds stored or operated in humid conditions require less protection. Low production costs: Water cooling channels are less affected by corrosion Heat transfer characteristics, and therefore cooling efficiency, are constant throughout the mould life, ensuring consistent cycle times. Safe mould use because of good toughness also in big dimensions

Heat treatable alloy of medium strength, good corrosion resistance and weldability.

Heat treatable, very high strength alloy. Very high fatigue strength.

E110 is a 1.8% Nickel Chromium Molybdenum case hardening steel combining core toughness and high case hardness after carburising and quenching.
