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.

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.
