Driveshafts require BÖHLER steels with high fatigue strength, torsional rigidity, and toughness. Key quality features include ultra-clean materials, controlled heat treatment, full traceability, and rigorous testing for reliable automotive and racing performance.
Driveshafts in automotive and high-performance racing applications are key powertrain components, transmitting torque under high rotational speeds, dynamic loading, and varying thermal conditions. Material requirements are therefore highly demanding, focusing on high fatigue strength, torsional rigidity, impact toughness, and resistance to vibration and wear. In racing environments, additional demands such as weight reduction, high-temperature stability, and consistent performance under extreme load cycles are critical for efficiency and reliability.
BÖHLER high-performance steels and alloys are specifically engineered to meet these requirements. Advanced alloyed steels, including quenched and tempered, case-hardening, and microalloyed grades, provide an optimized balance of strength, toughness, and fatigue resistance. Produced using advanced melting and refining technologies, BÖHLER materials ensure superior cleanliness, low inclusion content, and homogeneous microstructures, significantly enhancing durability under cyclic stress. Key quality features include precise control of chemical composition, certified traceability, and tightly controlled heat treatment processes to achieve defined mechanical and torsional properties. Additional process steps such as surface treatment or shot peening further improve fatigue life. Comprehensive testing, including torsional fatigue, mechanical verification, and non-destructive inspection, ensures consistent quality. BÖHLER materials enable reliable, lightweight, and high-performance driveshaft solutions for automotive and racing applications.
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.
