Shafts in energy applications require high-strength BÖHLER steels with excellent fatigue and toughness. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing for reliable long-term performance.

Shafts used in energy applications such as turbines, generators, and compressors are highly stressed components operating under continuous rotation, cyclic loading, and often elevated temperatures. Material requirements are therefore focused on high tensile strength, excellent fatigue resistance, fracture toughness, and long-term dimensional stability. In demanding environments, additional properties such as resistance to corrosion, creep, and hydrogen embrittlement are essential to ensure operational safety and extended service life.

BÖHLER high-performance steels and alloys are specifically developed to meet these requirements. Advanced low-alloy and quenched and tempered steels, as well as martensitic and precipitation-hardened grades, provide optimized strength-to-toughness ratios and superior fatigue performance. Produced via advanced melting technologies, BÖHLER materials offer exceptional cleanliness and homogeneous microstructures, reducing the risk of crack initiation under cyclic stress. Key quality features include tight control of chemical composition, certified material traceability, and validated heat treatment processes. Comprehensive mechanical testing, non-destructive inspection, and dimensional verification ensure consistent quality. BÖHLER materials enable reliable, efficient, and long-lasting shaft performance in demanding energy systems.
