... standby mode, it was recommended that the condenser tube material be upgraded to one with better general corrosion and SCC resistance. Based on corrosion resistance, availability, price, and compatibility with the existing Muntz metal tube sheets, 90Cu-10Ni (UNS C70600) was selected for retubing. The 70Cu...

... elements detected. In the base metal tube spectrum copper, nickel and iron were detected. The chemistry was in agreement with alloy C70600 (UNS), also known as 90-10 cupronickel [ 1 ]. Cupronickels are known for their resistance to seawater corrosion. They are used in seawater piping evaporators...

... that the following alloys do not have a tendency for stress corrosion cracking in auxiliary heat exchangers (oil coolers): 90Cu-10Ni, 70Cu-30 Ni, arsenical copper, Alloy 194, and aluminum bronze. As a result, the use of 90Cu-10Ni (B111-Alloy C70600) is recommended for the replacement tubes. In addition...

... that this may be due to the ratio of cathodic to anodic areas, where a single phase, for example, ferrite, is preferentially attacked relative to a large area of less susceptible material. Penetration rates of 17 mm/year (0.7 in./year) in United Numbering System (UNS) 30800 welds have been reported. Perforation...
