Abstract
The selection of stainless steels to prevent stress corrosion cracking (SCC) in hot sodium hydroxide solution containing small amount of sodium sulfide was determined by order of the critical temperature of SCC occurrence and by the electrochemical behaviour. SCC susceptibility of stainless steels might be governed by chemical compositions, the nickel and chromium content.It was possible to presume that SUS 310S had enough resistance to use in industry.In comparison with SCC behaviour of SUS304L conducted with various SCC test methods, the detecting SCC was able to reproduce with not only the Lehigh restraint test but also the slow strain rate tensile tests at the same test conditions as in the U-bend test.
