Duplex steel boasts a unique dual-phase microstructure, featuring roughly equal parts austenite and ferrite. This composition provides enhanced mechanical strength and impressive resistance to stress corrosion cracking, pitting, and crevice corrosion. Common grades of duplex steel include 2205 and 2507, with tensile strengths typically ranging from 620 to 850 MPa. This alloy also maintains excellent toughness at low temperatures and performs reliably in harsh, chloride-rich environments, striking a perfect balance between corrosion resistance and mechanical durability.
