Description
The stress corrosion cracking of Liquid Metal Fast Breeder Reactor sodium heated steam generators is a major concern due to sodium hydroxide contamination. Previous testing has shown that 2 1/4Cr-1Mo steel is immune to caustic stress corrosion cracking at temperatures greater than 3160C (6000F), but may be susceptible at lower temperatures. The present study was undertaken to determine the stress corrosion cracking susceptibility of 2 1/4Cr-1Mo steel in caustic in the temperature range of 660C (1500F) to 2320C (4500F). Three heats--conventional air melt, electroslag remelt, and vacuum arc remelt were tested. The slow strain rate test was chosen to determine the caustic stress corrosion cracking susceptibility of the alloy. This paper discusses the effect of melting practice, temperature, caustic concentration, heat treatment, and applied potential on the caustic stress corrosion cracking susceptibility of 2 1/4Cr-1Mo steel
