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.
Bu teknik özellik, çubuk, tel, dövme parça ve dövme hammaddesi şeklindeki korozyon ve ısıya dayanıklı bir çeliği kapsar. ESR kalitesinde, östenitik, çökelme sertleşmesi uygulanabilen demir-nikel-krom-molibden-titanyum alaşımlı bir çeliktir. Alüminyum ve titanyum alaşım elementleri, bu malzemenin metalik ara fazların oluşumu yoluyla yaşlandırma (çökelme sertleşmesi) işlemine tabi tutulmasını sağlar. Molibden ilavesi ise yüksek sıcaklıklarda mekanik özellikleri ve sürünme direncini artırır. Bu ürünler genellikle enerji üretim mühendisliğinde, örneğin 704 °C’ye (1300 °F) kadar orta seviyede mukavemet ve 816 °C’ye (1500 °F) kadar oksidasyon direnci gerektiren gaz türbinleri gibi parçalarda kullanılır, ancak kullanım alanları bunlarla sınırlı değildir.
