... The microstructure of the plate had a high degree of cleanliness ( Fig. 1d ). The deformation structure showed that the material was in the cold-worked condition, which was confirmed by Vickers hardness tests. Energy-dispersive x-ray analysis indicated a chemical composition corresponding to a type 316 stainless...

.... Vickers hardness tests (1-kg load) on hard-spot specimens showed no deviation from the as-failed hardness scatter band for temperatures up to 550 °C (1020 °F), but gave definitely lower values after retempering at or above 600 °C (1110 °F). A similar behavior occurred in specimens taken outside the hard...
