BÖHLER E108 is a 4%-Nickel-chromium-molybdenum steel for applications requiring high core strength, high toughness and for bigger dimensions. Hardness in carburized layer above 58 HRC. Service temperature max. 200°C. Non corrosion resistant.

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 M121 ISOPLAST is a remelted nickel-chromium-molybdenum case-hardening steel for components with increased requirements for toughness and core strength.

BÖHLER M130 is a nickel-chromium-molybdenum alloyed case-hardening steel with high core strength and very good toughness.

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 V132 is a premium aircraft-quality, low-alloy Ni-Cr-Mo steel in the form of bars, forgings and forging stock requiring high tensile and toughness values, particular in large cross sections in the hardened and tempered condition. These products have been used typically for parts requiring a through-hardening capability up to 3.5 inches (89 mm) in nominal thickness at time of heat treatment but usage is not limited to such applications. E.g. highly stressed components and parts for the aircraft industry, Tracks, helicopter shafts, bolts and screws.

BÖHLER V358 in the British Standard Aerospace Series is a 3% Cr-Mo-V nitriding steel offering a tensile strength of 1,320-1,470 MPa, combined with excellent hardenability for high core strength and develops a hard wear resistant case after surface treatment. The alloy is produced by vacuum arc remelting. (VAR) Typical applications are gear shafts and crankshafts with maximum diameter of 70mm for the aircraft industry and automtovie components.

BÖHLER W360 ISOBLOC is a material produced by the electroslag remelting process (ESR), which has been specially adapted for use at high tool hardnesses in the range of 51-57 HRC. Although the steel can be classified as a 5% chromium steel, the increased carbon and molybdenum content coupled with state-of-the-art manufacturing technology ensures that BÖHLER W360 ISOBLOC still shows a very good toughness and an exceptionally good thermal resistance, even at high hardness levels. These properties make the steel the perfect choice for smaller components in the die casting sector (e.g., mold inserts, cores, core pins, ejector pins, etc.). The material also is frequently the preferred choice for closed-die and open-die forging tools due to its high wear resistance. Because of this excellent wear resistance and the high toughness, BÖHLER W360 ISOBLOC is also frequently used for cold work applications and as a molding material for plastic injection molds. The Steel also is available as powder material for metal-3D-printing under the brand name BÖHLER W360 AMPO.

BÖHLER W460 VMR is a double vacuum arc remelted (VAR) material that has been specially adapted for use in the motorsport sector. The steel purity achieved by this special manufacturing technology, combined with the high strength, ensures that a very high fatigue strength can be guaranteed. The high purity also results in very good polishability, which makes the steel a good choice as a tool material for minting coins.
