China ramps up CHSN01 fusion magnet jacket for cryogenic reactors
China has produced 30 tons of cryogenic jacket material made from its CHSN01 steel in continuous lengths of about 5 km for use in Cable-in-Conduit Conductors for future fusion reactors. The jacket is designed for magnets that must endure strong fields and very low temperatures in advanced fusion devices. Mechanical tests at 4.2 K show the CHSN01 jacket reaches an average yield strength of
