The following is a discussion of the paper entitled “The Effect of Fluid Flow on the Stress Corrosion Cracking of ASTM A508 Cl 2 Steel and AISI Type 304 Stainless Steel in High Temperature Water” by H. Choi, F. H. Beck, Z. Szklarska-Smialowska, and D. D. Macdonald published in CORROSION, Vol. 38, No. 2, p. 76 (1982)
Discussion by J. Hickling, Allianz Zentrum fuer Technik, Federal Republic of Germany.
Choi, et al., are to be congratulated upon pointing out the considerable effects of fluid flow on stress corrosion cracking (SCC) in high temperature water, at least in the slow strain rate test. This is probably of considerable practical importance and has been ignored in much mechanistic work. The following comments relate only to the results obtained for ASTM A508 Cl 2 steel, the figure numbers referring to the original paper, except where stated otherwise.
