Rotors and Stators

Cobalt Alloy rotors and stators are commonly used in applications that involve high-speed rotation, such as in gas turbines, jet engines, and other types of machinery. STP alloy rotors and stators provide high performance, durability, and reliability in high-speed rotating machinery applications.

Additional information

Product Details:

STP is a kind of cobalt-chromium alloy that is known for its high wear resistance, high-temperature resistance, and excellent corrosion resistance. STP alloys are often used in high-performance applications where components must withstand harsh operating conditions.

In the context of rotating machinery, an STP rotor and stator refer to the use of cobalt alloys in constructing these components. A rotor is the rotating part of a machine, while a stator is a stationary part. STP rotors and stators are commonly found in pumps, compressors, and turbines, where the high wear resistance of STP alloy is beneficial for prolonging the life of the components.

STP alloy is often used in constructing the blades or vanes of the rotor and stator, as well as in the wear rings that help seal the gap between the rotor and stator. STP alloys are also used to coat the surfaces of these components to improve their wear resistance further.

Overall, the use of cobalt alloy in rotors and stators can help improve the performance, reliability, and longevity of rotating machinery in demanding applications.
