BÖHLER K455 corresponds approximately to the material 1.2550 (~60WCrV7, ~S1) in terms of the alloy concept. This classic matrix steel is characterized by high toughness, good machinability and polishability. BÖHLER K455 offers the advantage of simple heat treatment with low hardening temperatures and single tempering. BÖHLER K455 is widely used in the field of punching and cutting tools as well as in the field of embossing tools.

BÖHLER K600 corresponds to the material 1.2767 (45NiCrMo16). With its high nickel content, this material offers a very good combination of through hardenability and toughness. This results in a high resistance to impact and shock loads. BÖHLER K600 is used for a wide range of tools where high toughness is required. The material is used for forming and bending tools, cold shear blades for thick materials and for reinforcement rings. Due to its good polishability, BÖHLER K600 is also used for embossing tools, plastic molds and mold inserts for injection molding.

BÖHLER K700 corresponds to the material 1.3401 (X120Mn12) and belongs to the group of austenitic hard manganese steels. Unlike most tool steels, BÖHLER K700 is not used in the hardened and tempered condition. Due to the forces occurring in service, the resulting work hardening of the surface results in a high resistance to abrasive wear. BÖHLER K700 is weldable. However, the heat input must be kept as low as possible to avoid embrittlement of the material. The material is used in abrasive blasting and mining applications such as crusher jaws, beater bars, grate bars, linings, excavator teeth and chain rollers.

BÖHLER M310 ISOPLAST is a corrosion-resistant, martensitic chromium steel which, through electroslag remelting and optimization of the chemical composition, has a good homogeneity and a balanced hardness-toughness-corrosion resistance ratio.

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 M340 ISOPLAST corresponds to a corrosion-resistant, martensitic chromium steel with improved wear resistance. This is ideal for the application area of glass fiber reinforced plastics. In addition, the BÖHLER M340 ISOPLAST is approved for food and beverage contact.

BÖHLER M368 MICROCLEAN is a corrosion-resistant, martensitic chromium steel produced by powder metallurgy. Due to the alloy concept and the production route, the steel has a high wear resistance, high corrosion resistance and high toughness. In addition, BÖHLER M368 MICROCLEAN is approved for food and beverage contact.

BÖHLER M390 MICROCLEAN is a corrosion-resistant, martensitic chromium steel produced by powder metallurgy. Due to its alloy design, this steel has very high wear resistance and good corrosion resistance. In addition, BÖHLER M390 MICROCLEAN is approved for food and beverage contact.

BÖHLER N690 is a corrosion-resistant, martensitic chromium steel with a high carbon content and the addition of cobalt, molybdenum and vanadium. BÖHLER N690 is also approved for food and beverage contact.
