Abstract
A new nonmagnetic steel with yield strength in excess of 200 ksi and plane strain fracture toughness (KIC) in excess of 100 ksi √in. has been developed by the Electric Power Research Institute in collaboration with the University of California at Berkeley. The alloy has good resistance to cracking in presence of hydrogen and chloride environments. The properties are obtained in the asheattreated condition without the need for cold expansion as has been the practice in the past. It is anticipated that successful commercialization of the alloy for use as retaining rings can result in improved generator reliability, size capability and efficiency. This paper is a progress report on this significant development.
