LY Steel's hydropower steel falls within the category of medium-low pressure and medium-low temperature pressure vessels. The developed Q460CF-Q800CF series of high-strength steel with low welding crack sensitivity for hydropower stations can be used for pressure vessels, hydropower pressure pipelines, and structural components operating in temperatures ranging from -40°C to 100°C. It features high steel purity, low welding crack sensitivity (Pcm value), low carbon equivalent, and excellent welding performance, meeting the technical requirements for critical components such as volutes, pressure pipelines, and yoke rings in hydropower projects. It has the capability to supply large-scale hydropower stations and pumped storage power stations, making it another high-quality steel plate from LY Steel contributing to the global energy structure transformation!
