Nuclear Power

Manufacturer of the 15.673 m-diameter "Internet-famous Cosmic Ring"

In the nuclear power sector, we hold the world record for producing super-large forged rings with a hot-state diameter of 16 m. In 2019 and 2022, overcoming significant challenges and embracing substantial R&D risks, we collaborated with teams from the China Institute of Atomic Energy and the Institute of Metal Research, Chinese Academy of Sciences. By employing metal construction and near-net-shape forming technologies, we became the first to solve the global challenge of manufacturing 220-ton-grade 316 stainless steel billets with exceptional purity and homogeneity. This breakthrough enabled us to produce four 15.673 m-diameter austenitic stainless steel seamless forged rings for China's fourth-generation nuclear power plant, setting a new world record in the process.
