A Guide to Duplex Stainless Steel | What is It? - Unified ugiplex duplex stainless steel

Duplex stainless steels get their name from their two-phase microstructure. While exact ratios vary by grade, most duplex steels have a structure that is roughly 50-percent austenite and 50-percent ferrite. This gives duplex stainless many of the perks of austenitic and ferritic families of steel while also minimizing the weaknesses.(PDF) DUPLEX STAINLESS STEELS - ResearchGateAustenitic-ferritic stainless steels, more commonly known as duplex stainless steels, or DSS for short, consist of two basic phases. One is austenite, A, and the other is ferrite, F, present in ugiplex duplex stainless steel
