Recently, 800MPa hydropower steel of Ansteel passed technical examination by metallurgical and hydropower industry experts, chaired by China Iron and Steel Industry Association, which marks that Ansteel has the qualification to supply 800MPa hydropower steel to large-sized hydropower stations and pumped storage power stations and the market exploitation capability of the product is further improved.

Mainly used for manufacturing the spiral casing, pressure steel pipe and other important structural parts in hydropower project, 800MPa hydropower steel should have high strength and toughness, good cold deformability and weldability. In recent years, with the implementation of sustainable development strategy and western development strategy, extra large-sized hydropower station projects and pumped storage hydropower projects start construction one after another. 800MPa hydropower steel has a great market demand. Closely following the demand, Ansteel actively carries out research and development on the basis of the characteristics of its process and apparatus and provides supports for updating hydropower steel.

The experts think that 800MPa hydropower steel by Ansteel adopts the design concept of high strength and toughness, combines with clean steel melting, control rolling and heat treatment process so as to realize the strength and toughness matching of 800MPa hydropower steel. Due to the reasonable production process, it has stable and batch production capability; with good weldability, the plate could meet the requirement of large-sized hydropower project specification. Therefore, Ansteel has the supply capability for large-sized hydropower stations and pumped storage hydropower stations.
