Duplex steel round bars are a type of alloyed steel that features a balanced microstructure of austenite and ferrite, typically enriched with chromium, nickel, molybdenum, and nitrogen. This unique composition grants them exceptional corrosion resistance, especially against pitting and stress corrosion cracking, all while maintaining impressive mechanical strength. Compared to traditional austenitic steels, duplex steel round bars boast higher yield strength, along with good toughness and fatigue resistance. They also excel in weldability and dimensional stability, making them perfect for challenging structural and pressure-bearing applications.
