Duplex stainless steel plate
Duplex stainless steel plate features a dual-phase microstructure (austenite + ferrite), delivering a unique combination of high mechanical strength and excellent resistance to corrosion.
Compared to standard austenitic stainless steels (like 304/316), duplex grades offer higher yield strength and better resistance to stress corrosion cracking, especially in chloride-rich environments.
