A review of what is understood about the relationship between cold work and resistance to stress corrosion cracking in carbon and low alloys steels was performed. This review was broken up into five sections containing literature citations of field failures, three categories of laboratory results and test methods. A discussion follows which presents the known aspects of cold work with areas identified in which knowledge is lacking. The areas in which further research is suggested include (1) the effects of small amounts (the 1% - 4% range) of cold work on SSC resistance, (2) the effect of steel microstructure (Q&T versus as-hot worked or as-normalized), (3) the relative merits of the different SSC tests in measuring the effect of cold work, and (4) the impact of plastic strain on SSC tests. This review came to the conclusion that it was generally accepted that cold working reduces resistance to SSC in carbon and low alloy steels and that this reduction in resistance can be removed by stress relieving. It was also found that most of the published field failures which cited cold work were due to mechanical damage.
