| Popis: |
A series of shielded metal arc electrodes was fabricated and the mechanical properties of the resultant welds were measured. The compositions are based on a high Mn, high N version of a type 308 electrode, to which additional Mn, N, Ni and Mo were added. The strength was measured at 4, 76 and 298 K, and the Charpy V-notch absorbed energy was measured at 76 K. The strength of the welds matched or exceeded that strength of the base metal, but fell short of the Charpy V-notch absorbed energy. |
