Abstract
The through-thickness mechanical properties of heavy-section 316LN forged stainless-steel plate were measured at 4 K. The properties studied were tensile and fracture toughness. Grain size, hardness, and chemistry variations were also obtained. The forged material came from cores of a 700-mm-thick plate for the MIT Alcator C-MOD. The average tensile yield strength was 889 MPa and the maximum variations from the average surface value were ± 5%. The average fracture toughness (estimates of K Ic from J Ic measurements) of the forging was unusually high, 471 MPa/m, with consistent values having been obtained from the interior of the forging, but variations of 25% from the average interior value were found.
