Blades and shafts require high‑strength BÖHLER steels and alloys with excellent fatigue and temperature resistance. Key quality features include ultra‑clean materials, full traceability, controlled heat treatment, and rigorous inspection for reliable performance.
Blades and shafts for turbines and compressors operate under extreme mechanical and thermal conditions, requiring materials with outstanding strength, fatigue resistance, and long‑term stability. High rotational speeds, cyclic loading, and exposure to elevated temperatures demand precise control of material properties and microstructure to ensure safe and reliable performance. Material requirements focus on high tensile strength, creep resistance, fracture toughness, and resistance to wear and corrosion.
BÖHLER high‑performance steels and alloys are specifically engineered to meet these challenges. Advanced martensitic, precipitation‑hardened, and high‑alloy steels provide optimized combinations of strength and toughness, while nickel‑based alloys are used for elevated‑temperature applications. Cleanliness, achieved through advanced melting technologies, ensures minimal inclusions and superior fatigue life. Quality features include strict chemical composition control, certified material traceability, and validated heat treatment processes. Comprehensive non‑destructive testing, dimensional inspection, and metallurgical verification guarantee consistent performance. BÖHLER materials enable turbine and compressor components to achieve maximum reliability, efficiency, and extended service life in demanding industrial and aerospace environments.
Používa sa pre vysoko namáhané diely plynových turbín, pohonov, čerpadiel a jadrových reaktoroch. Používa sa pre pretláčacie nástroje pre meď a medené zliatiny, pre dierovanie za tepla ocelí a mosadzných zliatin, pre kovacie zápustky a nože pre strihanie za tepla.

Prečítajte si viacThis specification covers a corrosion and heat resistant steel in the form of bars, wire, forgings and forging stock. It is an austenitic, precipitation hardenable, iron-nickel-chromium-molydenum-titanium steel of ESR quality. Alloying elements of aluminium and titanium allow this material to undergo precipitation hardening (ageing) through the formation of intermetallic phases. The addition of molybdenum increases the mechanical properties and resistance to creep at high temperatures. These products have been typically used for parts in power generation engineering i.e. gas turbines requiring moderate strength up to 704 °C (1300 °F) and oxidation resistance up to 816 °C (1500 °F), but their use is not limited to such applications.
