Product Inquiry

Product Introduction:

　　Hydropower steel of is applied in low and medium pressure, low and medium temperature pressure vessels. Q460CF-Q800CF low welding crack sensitivehigh-strength steel for hydropower station developed by can be used for -40 ~ 100℃ pressure vessels, hydropower pressure steel pipes and other equipment and structural parts. With high steel cleanliness, low welding crack sensitivity (Pcm value), low carbon equivalent and excellent welding properties, it meets the technical requirements of important components such as volute, pressure steel pipe and magnetic yoke ring in hydropower projects, and has the ability to supply large hydropower stations and pumped storage power stations, which is the high-quality steel of contributing to the transformation of global energy structure!
