What is "norem"

NOREM is a hardfacing material developed by Electric Power Research Institute (EPRI) to deal with radiation safety issues associated with the use of cobalt alloys in nuclear power station coolant systems (see stellite for a discussion of the problem). It is a solid-solution strengthened austenitic matrix with a continuous network of eutectic and non-eutectic carbides at the grain boundaries. It is intended to be deposited by various welding processes.
