This specification covers silver-indium-cadmium alloy for use as a control material in light-water nuclear reactors. The use of this material in applications is excluded where material strength of this alloy is a prime requisite. Also, this material must be protected from the primary water by a corrosion and wear resistant cladding. The identity of each lot by melt number shall be maintained at all stages of manufacture. Parts produced to this specification shall be made from billets by hot working and cold finishing to size. The cold-finished parts shall be produced to the finish condition and dimensions as specified. The surface of the cold-finished part shall be free of oxides, grease, oil, residual lubricants, inclusions, and other extraneous materials. Surface defects such as folds, cracks, seams, slivers, and blisters shall be cause for rejection.
