This course is based on Practical Guidelines for the Fabrication of Duplex Stainless Steels (Third Edition, 2014), published by the International Molybdenum Association (IMOA).

It provides practical, experience-based guidance for fabricators, engineers, inspectors, and end users involved in the specification, fabrication, welding, and quality control of duplex stainless steel products. The publication addresses the unique metallurgical characteristics of duplex stainless steels and explains how composition, phase balance, thermal history, and fabrication practices influence mechanical properties, corrosion resistance, and in-service performance.

The course focuses on fabrication-related topics including forming, machining, welding, heat treatment, and post-fabrication cleanup, with particular emphasis on avoiding detrimental phases and preserving corrosion resistance and toughness. Drawing on industry experience and established standards, it supports informed fabrication and material handling practices that enhance reliability, reduce fabrication-related failures, and ensure consistent performance of duplex stainless steels in demanding applications.
