ESAB technical paper for welding duplex stainless steels

A team of engineers from ESAB Welding & Cutting Products’ Process Centre in Dubai, United Arab Emirates, demonstrated that the pitting resistance equivalent number (PREN) value of duplex stainless steel alloys may lead to a misleading prediction of pitting corrosion resistance in the as-welded material. The research results, published a technical paper in the April 2020 issue of Saudi Journal of Engineering & Technology, conclude that in the event of an imbalance of delta ferrite and austenite volume fraction, the chemical composition of the phases may be very different from that of the alloy.
