Gears require BÖHLER steels with high fatigue strength, wear resistance, and surface hardness. Key quality features include ultra-clean materials, controlled heat treatment, full traceability, and rigorous testing for reliable automotive and racing performance.

Gears used in automotive and high-performance racing applications operate under extreme mechanical stresses, including high contact pressures, cyclic loading, and varying thermal conditions. Reliable torque transmission and efficiency require materials with outstanding fatigue strength, wear resistance, and surface durability. Material requirements therefore focus on high hardness at the tooth flank, a tough core to withstand dynamic loads, and resistance to pitting, scuffing, and micro-cracking. In racing environments, additional demands such as weight optimization and thermal stability are critical for peak performance and reliability.

BÖHLER high-performance steels and alloys are specifically engineered to meet these demanding gear requirements. Advanced case-hardening steels, nitriding steels, and high-strength alloyed grades provide an optimal combination of surface hardness and core toughness. Produced using advanced melting and refining technologies, BÖHLER materials ensure superior cleanliness, low inclusion content, and a homogeneous microstructure, significantly enhancing fatigue life and load capacity. Key quality features include precise chemical composition control, certified traceability, and tightly controlled heat treatment processes to achieve consistent case depth and hardness profiles. Surface engineering solutions further improve wear resistance. Comprehensive testing, including fatigue, hardness, and non-destructive inspection, ensures reliable and repeatable gear performance. BÖHLER materials enable efficient, durable, and high-performance gear solutions for automotive and racing applications.
