| | The word duplex is based on the concept of austenite and ferrite formulated in the same material. The user may require a briefing about the material's composition, but in general, the most important aspect is what it will do in use. Fabricators really are not interested in chemical composition or phase diagrams. They want to know a material's advantages and disadvantages and how difficult or easy it is to fabricate. Metallurgists are interested in the material's composition and the end usage. They may be able to investigate the mechanical, physical, and chemical properties and discover advantages or disadvantages for a particular application. The following information is intended to provide a useful, but not highly technical, characterization of duplex and superduplex stainless steels' usefulness, advantages, disadvantages, and fabrication ease. | |
