The Duplex 2205 Stainless Steel Rod is a premium-grade duplex stainless steel product designed for superior strength and corrosion resistance. With a dual-phase microstructure of austenite and ferrite, it combines the best attributes of both – offering excellent mechanical performance, high resistance to stress corrosion cracking, and exceptional durability in harsh environments. This makes it an ideal choice for applications in chemical processing, marine engineering, and oil & gas industries.
Outstanding Corrosion Resistance: Excellent resistance to pitting, crevice, and chloride stress corrosion cracking.
High Strength: Nearly twice the yield strength of standard austenitic stainless steels such as 304 or 316.
Excellent Weldability: Compatible with most standard welding techniques with minimal risk of hot cracking.
Superior Fatigue Resistance: Performs reliably under cyclic stress conditions.
Good Toughness: Maintains ductility and toughness even at sub-zero temperatures.
Chemical Processing: Heat exchangers, evaporators, and reaction vessels exposed to corrosive chemicals.
Marine Industry: Propeller shafts, pumps, and structural components exposed to seawater.
Oil & Gas: Pressure vessels, pipeline systems, and offshore platforms.
Pulp & Paper Industry: Digesters, bleaching systems, and other chloride-exposed environments.
Power Generation: Components operating under high stress and temperature conditions.
Combines high mechanical strength with corrosion resistance.
Extends service life in marine and industrial chemical environments.
Reduces maintenance and replacement costs due to superior durability.
Performs well under high pressure, temperature, and chloride exposure.
Sustainable material with high recyclability and long operational lifespan.
The Duplex 2205 Stainless Steel Rod offers an exceptional balance of strength, corrosion resistance, and cost-effectiveness. Its duplex structure makes it the preferred material for industries requiring long-term performance under severe conditions. Whether in offshore engineering, chemical plants, or marine structures, Duplex 2205 provides unmatched reliability and structural integrity.
