Atkins Webinar on Duplex stainless steels

Atkins Webinar on Duplex stainless steels: factors influencing fabrication and qualification (Lessons learnt from various industries)

Phase balance is important in duplex stainless steels as it helps to impart optimum mechanical properties and corrosion resistance, and also in austenitic stainless steel welds to improve weldability. It is necessary to assure that phase balance is still within acceptable ranges in the heat-affected zone and/or the weld metal after welding. Quality control of welded duplex and austenitic stainless steels usually requires confirmation of an acceptable phase balance, by ferrite measurement. Ferrite measurement practice will be presented, in terms of existing, established magnetic and metallographic techniques and recent advances in materials characterisation tools.
