CALL FOR PAPERS for Duplex World Seminar & Summit, November 2022, Rotterdam, the Netherlands
In a world of rising prices, duplex appears more attractive than ever, by James Chater, Duplex World
As inflation once again takes hold, duplex stainless steel can be seen as an attractive alternative to higher-alloyed materials in many applications.
Improved 22% chromium duplex stainless steel, by John Grocki, Sandra Le Manchet, Anne Higelin, Industeel (ArcelorMittal group)
Industeel recently developed a new controlled chemistry 2205 duplex stainless steel with enhanced weldability compared to the conventional 2205 material and improved low temperature toughness properties.
Sigma phase: a metallurgical challenge when welding duplex, by F Ahnia, Department of Mechanical Engineering, University A/Mira Bejaia, Algeria & F Khoshnaw, Senior Lecturer, School of
Engineering and Sustainable Development, De Montfort University
Examining new types of failures and metallurgical aspects, especially during manufacturing processes requiring high temperatures such as welding and heat treatment, have led researchers to realise that high strength alone is not sufficient to meet the requirements for a reliable component.
Continuously Stirred Tank Reactors (CSTR), by Stallkamp
A German fabricator has ventured into producing duplex CSTR tanks. At 20 meters in height, this demands a steady hand and attention to detail.
Positive results for 3D-printed duplex connectors, by MX3D/Takenaka
Large-scale 3D-printing company MX3D has successfully produced a structural connector in duplex, designed in collboration with engineers from Takenaka.
Duplex stainless steel quality – ASTM A923 vs ISO 17781, by Roger Francis, RF Materials & Glenn Byrne, Rolled Alloys
Two standards are available for users considering applying additional testing to duplex stainless steels: ASTM A923and ISO 17781.
