JT-60SA TF coil replacement forged material

The European Joint Undertaking for ITER and the Development of Fusion Energy ('Fusion for Energy')

This technical specification concerns the supply of a number of forged blocks for the manufacturing of the JT-60SA toroidal field coil casings. The materials required are 36 large forged blanks (1 790 x 1 560 x 280 mm), and 41 small forged blanks (350 x 380 x 480 mm), both rough-machined. The blanks must be manufactured from 316L stainless steel, with narrowed-down chemical composition requirements, assurance of material ductility at cryogenic temperatures, total absence of non-austenitic phases, forging manufacturing method, including a minimum reduction ratio of 6, and urgent delivery schedule foreseeing the first delivery of 2 large forged blanks (with 9 small forged blanks) delivered 3 months after contract signature and the subsequent delivery of the same lot size every subsequent month.
Potential suppliers are requested to have past proven experience of procurement of large forged parts of austenic steel for the specific application in superconducting magnets operating at cryogenic temperature.
