Light, intercrystalline corrosion attack on a vacuum flange. Presumably, a little moisture from the vacuum chamber was sufficient here, as it was not operated continuously. The age-hardenable alloy exhibits poor corrosion resistance in the weather and in seawater. The material is often used for machining.
