The papers in this volume represent the first discussion of its kind on the subject of the “Effects of Residual Elements on Properties of Austenitic Stainless Steels.” The authors have enumerated the sources from which some of the residual elements originate and evaluated their effects on the products made of these steels. During the more than fifty years in which these alloys have been commercially produced in the United States, numerous restrictions on the various elements have been written into specifications, often without either technical knowledge or justification, and probably most frequently on the basis of unfounded opinions. Now for the first time, a group of technical experts, metallurgists, and engineers, have presented documented evidence that many of the residual elements have little or no adverse influence on the metal's behavior in the many applications for which this important family of stainless and heat resisting steels is utilized. For the first time also, the technical literature is augmented by this present series of authoritative discussions. It is the consensus that in general only one area will now need additional work and that is in the field of welding. The view is projected in one of the papers in this symposium that at the present time it is not possible to evaluate the beneficial or harmful effects of many of the residual elements in welded structures. In other areas, such as fabricating or resistance to corrosive environments, the data here assembled indicate that many of the elements may indeed be beneficial rather than detrimental. The authors have presented their views clearly and succinctly. They are to be commended for these valuable contributions to the literature in a field where silence has too long been the rule.
