                Fabricating Duplex Stainless Steel

                Duplex stainless steels differ significantly from austenitic stainless steels in the following important respects:

                1) Chemical composition

                2) Mechanical properties

                3) Formability

                4) Weldability

                5) Machinability

                The International Molybdenum Association (IMOA) has a compiled practical guide to the behaviour of these steels in fabrication. It can be downloaded from:

                Practical Guidelines for the Fabrication of Duplex Stainless Steels

                The chemical compositions and mechanical properties of these steels can be found in the articles referenced below. The common steels covered in the European Standards are:
