Two very successful conferences - in Glasgow and Beaune - were held on duplex stainless steels during the first half of the '90s. This book takes keynote papers from each, and develops and expands them to bring the topics right up to date. There is new material to cover grades, specifications and standards, and the book is fully cross-references and indexed. The first reference book to be published on the increasingly popular duplex stainless steels, it will be widely welcomed by metallurgists, design and materials engineers, oil and gas engineers and anyone involved in materials development and properties. The first reference book on this relatively new engineering material Based on keynote papers from major international contributors Covers grades, standards and specifications

The nature and the effect of the unmixed zone in dissimilar fusion welds, especially its significance with regard to corrosion resistance, has been studied in this Welding Research Council-sponsored program. Three types of super-austenitic stainless steel (high Mo) (AL-6XN, 254SMO and 654SMO) and five types of fully austenitic nickel-based weld filler metals (Inconel 625, C-22, C-276, 686CPT, and P16) were evaluated. Shielded metal arc (SMA), gas metal arc (GMA), gas tungsten arc (GTA) (filler added), and gas tungsten arc (GTA) autogenous welding processes were used for fabricating weldments of each super-austenitic stainless steel. The employment of these welding techniques provided a full range of unmixed zone formation. The unmixed zone formation was metallographically evaluated using both optical light microscopy (OLM) and scanning electron microscopy (SEM) with varied etchants and etching techniques. The pitting corrosion behavior of the unmixed zone was evaluated using immersion corrosion tests in 10% FeCl3.
