@@@@X12CrMoWVNbN10-1-1 steel has been widely used in manufacturing of the large-sized rotor forg?ings for supercritical and ultra-supercritical steam turbine applications in our country. This kind of product is now in great demand on the domestic market, but still relies on import at present. Chemical composition, purity, micro?structure and mechanical properties of the imported X12CrMoWVNbN10-1-1 steel are not clear yet. For this rea?son, a sample taken from imported rotor of X12CrMoWVNbN10-1-1 was tested and analyzed, in order to provide the reference data for the localization of this steel.
