Specifiers and fabricators requiring the unique combination of high corrosion resistance and outstanding material strength provided by duplex stainless steels now have freely available to them a definitive guide to selecting and working with duplex grades.

A major update of ‘Practical Guidelines for the fabrication of Duplex Stainless Steels’ brings together in one publication experience from around the world. It goes beyond the first and second generations of these materials also taking into account the latest developments in lean duplex and hyper duplex grades.

Mechanical and physical properties as well as corrosion resistance data are presented in greater detail. Detailed fabrication guidelines encompass a variety of fabrication processes, among them cutting, forming, machining and welding. Alternative joining techniques such as adhesive bonding, soldering and brazing are also discussed. Overall the publication contributes to a better understanding of the fabrication parameters.

Typical applications requiring the special properties of duplex grades include flue gas desulphurization, sewage treatment and desalination, oil and gas applications and biofuel production.

A special chapter has been dedicated to end user specifications and quality control. The publication helps the reader to analyse the conditions under which the material will need to perform and provides guidance on the selection of the most appropriate grade.
