Duplex Steel Valves are crafted from stainless steel grades that boast a balanced microstructure of austenite and ferrite, like Duplex 2205 or Super Duplex 2507. This unique dual-phase structure provides remarkable strength—often double that of standard austenitic stainless steels—and exceptional resistance to issues like chloride-induced stress corrosion cracking, pitting, and crevice corrosion. Typically, these valves show tensile strengths between 620 and 900 MPa and maintain their mechanical integrity even in high-temperature and high-pressure systems. Plus, Duplex Steel Valves are known for their excellent weldability, fatigue resistance, and long service life, even in the harshest industrial settings.
