Steam valves require high-performance BÖHLER steels with excellent creep, corrosion, and thermal fatigue resistance. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing for reliable operation.
Steam valves in energy applications are critical components exposed to high temperatures, high pressures, and aggressive media. They must ensure tight sealing, reliable operation, and long service life under continuous or cyclic loading conditions. Material requirements therefore focus on high-temperature strength, creep resistance, oxidation resistance, and excellent corrosion behavior in steam environments. In addition, resistance to thermal fatigue and dimensional stability are essential to maintain functional integrity over extended operation periods.
BÖHLER high-performance steels and alloys are specifically designed to meet these demanding requirements. Advanced creep-resistant steels, martensitic and ferritic stainless steels, as well as selected high-alloy materials provide an optimized balance of strength, toughness, and resistance to thermal degradation. Produced using advanced melting technologies, BÖHLER materials ensure superior cleanliness and homogeneous microstructures, reducing the risk of failure under long-term exposure. Key quality features include strict control of chemical composition, certified material traceability, and validated heat treatment processes. Comprehensive testing, including non-destructive inspection and mechanical verification, guarantees consistent performance. BÖHLER solutions support safe, efficient, and durable steam valve operation in modern power generation systems.
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.
