This paper focuses on mechanical tests on the ITER TF jacket 316LN stainless steel material. During manufacture the conductor will be compacted, spooled and aged at approximately 650 °C after cable insertion. Therefore, sample jackets were prepared under compaction, stretching and annealing in order to simulate the manufacturing process of TF coils. The mechanical properties of the given material were measured at 4.2 K and 300 K. Young’s modulus, yield strength (0.2% offset) and elongation are reported. SEM images showed that the TF jacket had more pronounced ductile behavior. The elongation at failure is more than 30% at cryogenic temperature, showing that the TF jacket has high mechanical performance. It is concluded that the results complies with ITER requirements.
► Make tensile test on ITER TF jacket.
► The tested TF jacket has high performance on tensile property, especially for cryogenic property.
► The elongation at failure for the tested TF jacket is about 33 than ITER requirements (20%).
