Form: Rod
Material: Stainless Steel
Commodity: Alloys
Diameter:

Annealed
Super Duplex Stainless Steel Rod (Fe/Cr 25/Ni 7/Mo 4) combines high strength with superior resistance to stress corrosion cracking, pitting, and crevice attack in aggressive environments. Its dual-phase microstructure of austenite and ferrite provides excellent toughness and weldability, while high chromium and molybdenum content ensure resilience against chloride-induced corrosion. Industries such as offshore engineering, chemical processing, and marine technology employ super duplex rods for components exposed to seawater and harsh chemicals. Specific applications include pump shafts, subsea connectors, and pressure vessel supports. In research, these rods are studied for fatigue resistance, microstructural stability under thermal cycling, and performance in high-chloride or acidic environments. Their ability to deliver both strength and corrosion resistance makes super duplex stainless steel rods an indispensable choice for critical infrastructure and advanced materials engineering.
