Third edition of duplex fabrication brochure published


The International Molybdenum Association (IMOA) has published the third edition of ‘Practical Guidelines for the Fabrication of Duplex Stainless Steels’. Significantly revised and updated from the second edition published in 2009, the brochure includes a new chapter on weld overlay, new grades and information on the new formable duplex stainless steels.

The classification of duplex stainless steel now includes two categories of lean duplex grades (lean duplex and molybdenum-containing lean duplex). Product names, specifications and designations have also been updated in the appendices.

Dr Nicole Kinsman, Technical Director, said: “The second edition has been by far our most popular website download and has been translated into seven languages other than English, including Chinese, Japanese and Spanish. Although we have retained the overall chapter structure in the new edition, the text has been comprehensively reviewed and we have added four extra pages and several new images.”

The third edition was officially launched at the Duplex Seminar and Summit 2014 in Stresa, Italy, and is available as a free PDF download from the IMOA website.  Hardcopies can be ordered from at no charge.



Notes for editors

IMOA is a non-profit trade association representing the interests of most of the world’s molybdenum producers and converters, as well as consumers and traders.  

Molybdenum is added to steels and cast irons to improve strength, toughness, hardenability and weldability for numerous applications in the automotive, shipbuilding, construction, mining, chemical, oil & gas and energy generation industries.    

In stainless steels and superalloys, it improves corrosion resistance and high-temperature performance and finds uses in many industrial applications.  It is also used in a variety of products from catalysts and lubricants to pigments and paint.
