Turbo Chargers

Turbochargers require BÖHLER steels and alloys with high-temperature strength, fatigue resistance, and oxidation resistance. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing for reliable high-speed performance.

Turbochargers in the automotive industry operate under extremely demanding conditions, including very high rotational speeds, elevated temperatures, and exposure to exhaust gases and aggressive media. Critical components such as shafts, wheels, and housings must withstand severe thermal and mechanical stresses while maintaining precise balance and dimensional stability. Material requirements therefore focus on high-temperature strength, excellent fatigue resistance, creep resistance, and oxidation and corrosion resistance. In addition, materials must provide stability under rapid thermal cycling and resistance to wear in high-speed environments.

BÖHLER high-performance steels and alloys are specifically engineered to meet these challenges. Advanced high-alloy steels, martensitic and precipitation-hardened grades, as well as nickel-based alloys provide an optimized combination of strength, thermal stability, and durability. Produced using advanced melting and refining technologies, BÖHLER materials ensure exceptional cleanliness, low inclusion content, and homogeneous microstructures, which are critical for high-speed fatigue performance. Key quality features include strict control of chemical composition, certified traceability, and precisely controlled heat treatment processes to achieve consistent mechanical and thermal properties. Comprehensive testing, including high-temperature behavior, fatigue performance, and non-destructive inspection, ensures reliable turbocharger operation. BÖHLER materials enable efficient, durable, and high-performance turbocharger solutions.
