Duplex and Super Duplex Stainless Steels
High-performance alloys for demanding industrial environments
Duplex and super duplex stainless steels feature a dual-phase structure—approximately 50% ferrite and 50% austenite—which grants them superior mechanical performance and resistance to localized corrosion (pitting, crevice, and stress corrosion cracking) compared to standard stainless steels like 316L.

Duplex Steels feature a dual-phase microstructure—roughly 50% ferrite and 50% austenite. This metallurgical balance significantly improves resistance to pitting corrosion, stress corrosion cracking, and delivers mechanical strength far superior to conventional stainless steels like 316L.
-
Super Duplex Steels are an advanced version of Duplex grades, with higher levels of chromium, molybdenum, and nitrogen. These enhancements provide even greater corrosion resistance, particularly in highly aggressive environments such as hydrochloric acids or marine applications.
These alloys are widely used in demanding sectors including offshore, petrochemicals, nuclear energy, chemical processing, marine industries, and energy production systems.
Why choose Duplex and Super Duplex Stainless Steels?
Duplex and super duplex steels are the go-to materials for complex industrial applications where corrosion resistance, mechanical strength, and service life are critical. Their mixed-phase structure offers a unique blend of performance, cost-efficiency, and fabrication ease.
Exceptional corrosion resistance
Unmatched resistance to corrosion in aggressive environments, including marine, chloride-rich, and chemical settings—far superior to conventional stainless steels.
Outstanding mechanical properties
High yield and tensile strength, ideal for components under mechanical stress, while maintaining good ductility.
Long-lasting durability in harsh conditions
Excellent resistance to cracking, pitting, and fatigue, ensuring reliability in critical infrastructures over time.
Excellent Corrosion Resistance
Titanium alloys provide exceptional resistance to corrosion, even in marine, chemical, and acidic environments, making them ideal for medical and marine applications.
Reduced maintenance costs
Naturally resistant to chemical attack and wear, these alloys help minimize downtime and maintenance, lowering long-term operating costs.
Thermal stability & weldability
Duplex steels maintain their structure and performance after thermal processing, and can be welded using standard techniques with appropriate precautions.
