Duplex 2205 Round Bar
Duplex 2205 Round Bar is a high-performance stainless steel product known for its exceptional strength and corrosion resistance. This alloy combines the benefits of austenitic and ferritic stainless steels, offering a balanced microstructure that enhances durability in demanding industrial environments. Its round bar form makes it ideal for manufacturing precision components that require both toughness and reliability.
Characterized by a nominal composition of approximately 22% chromium, 5% nickel, and 3% molybdenum, this material exhibits superior resistance to pitting and stress corrosion cracking. The duplex structure ensures a yield strength nearly twice that of conventional austenitic stainless steels, making it suitable for heavy-duty applications. Typical diameters range from small precision sizes to larger bars, catering to diverse machining and fabrication needs.
Industries such as oil and gas, chemical processing, marine engineering, and power generation frequently utilize these bars for shafts, fasteners, valves, and structural components. Their ability to withstand harsh environments, including chloride exposure and high temperatures, extends operational life and reduces maintenance costs. Additionally, the material’s weldability and machinability support complex engineering requirements.
Manufactured under stringent quality control standards, these bars comply with international specifications like ASTM A182 and EN 10088. This ensures consistency in mechanical properties and chemical composition, critical for global supply chains. Export-ready packaging and certification protocols facilitate seamless delivery to overseas industrial clients, meeting both regulatory and logistical demands.
For industrial buyers seeking reliable, corrosion-resistant round bars, this duplex stainless steel solution offers an optimal blend of performance and cost-effectiveness. Its versatility and robust physical properties make it a preferred choice for critical applications requiring long-term durability and structural integrity.

Manufacturing Process & Heat Treatment of Duplex 2205 Round Bar
Annealing
The annealing process for Duplex 2205 round bar involves heating the material to a temperature range of 1020°C to 1100°C, followed by controlled cooling. This process reduces internal stresses and improves ductility, making the material more workable for subsequent manufacturing steps.
Forging
Forging of Duplex 2205 is performed at elevated temperatures, typically between 1000°C and 1200°C. This process enhances the mechanical properties of the steel by refining the grain structure, resulting in improved strength and toughness.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Oil or Water | To increase hardness and strength |
| Tempering | 600 - 800 | Air | To relieve stresses and improve toughness |
| Stress Relieving | 300 - 500 | Air | To reduce residual stresses from machining |
The combination of these processes results in Duplex 2205 round bars that exhibit excellent mechanical properties and corrosion resistance, making them suitable for a wide range of industrial applications.
