RASEROKA, M.S.  and  PISTORIUS, P.C.. Controlled chloride cracking of austenitic stainless steel tube samples. J. S. Afr. Inst. Min. Metall. [online]. 2009, vol.109, n.7, pp.411-416. ISSN 2411-9717.

An experimental rig has been constructed to produce chloride stress corrosion cracks in Type 304L stainless steel tube samples. The samples are to be used to test possible in situ repair methods in future work. The factor which influences the time to failure most strongly is the sample temperature; the distribution of cracks within the sample is affected by local temperature variations and by the position of the water line. Low-frequency oscillations in stress, caused by the on-off temperature controller, did not appear to influence cracking in these tests
