Duplex Steel
Duplex Steel
Duplex steel is an advanced alloy that combines the strength of ferritic and the corrosion resistance of austenitic stainless steels. Its dual-phase microstructure provides excellent toughness, high yield strength, and superior resistance to stress corrosion cracking. These qualities make it ideal for demanding applications exposed to chloride-rich or high-pressure environments. Duplex steels also offer better weldability, durability, and cost efficiency compared to conventional grades.
At Apar Alloys, we supply and stock a comprehensive range of Duplex steel grades sourced from reputed global mills. Our materials meet international standards and are trusted across oil & gas, marine, chemical, and desalination industries. We focus on delivering reliable, performance-driven solutions tailored to specific project requirements. As a trusted supplier and stockist, we ensure certified quality, consistency, and on-time delivery with every supply.

Characteristics of Duplex Stainless Steel
- High Strength & Toughness:About twice the strength of standard austenitic stainless steels.
- Excellent Corrosion Resistance:Exceptional resistance to pitting, crevice, and chloride stress corrosion cracking.
- Good Weldability: Suitable for standard welding techniques with minimal risk of cracking.
- Improved Fatigue Strength:Performs reliably in high-stress and cyclic environments.
- Balanced Microstructure:Combines the ductility of austenitic and the strength of ferritic stainless steels.
- Superior Resistance to Erosion & Abrasion:Ideal for harsh and abrasive service environments.
What Makes Stainless Steel Duplex
Duplex stainless steels derive their name from their dual-phase microstructure, consisting of both austenite and ferrite in roughly equal proportions. This structure is achieved by balancing chromium (18–28%), nickel (4–9%), molybdenum, and nitrogen. The combination results in a material that offers the corrosion resistance of austenitic steels and the strength of ferritic steels, without compromising on toughness. Duplex grades are magnetic due to their ferritic content and exhibit superior resistance to chloride stress corrosion cracking, making them ideal for harsh, corrosive, and high-pressure environments.
