Duplex 2101 Sheet


Duplex 2101 Sheet is a high-performance stainless steel alloy known for its exceptional strength and corrosion resistance. This duplex stainless steel grade combines a balanced microstructure of austenitic and ferritic phases, offering enhanced mechanical properties and improved resistance to stress corrosion cracking compared to standard stainless steels. Typically supplied in sheet form, it is widely used in environments where durability and reliability are critical.
Manufactured to precise industry standards, these sheets exhibit a tensile strength ranging from 620 to 850 MPa and a yield strength of approximately 450 MPa. The material's composition, including around 21% chromium and 1.5% molybdenum, contributes significantly to its resistance against chloride-induced corrosion and pitting, making it suitable for marine and chemical processing applications. Thicknesses and dimensions are customizable to meet specific project requirements.
Industrial sectors leverage this alloy for fabricating equipment such as pressure vessels, heat exchangers, and storage tanks. Its excellent weldability and formability enable seamless integration into complex assemblies without compromising structural integrity. Additionally, the superior fatigue resistance and thermal conductivity make it an ideal choice for applications exposed to fluctuating temperatures and mechanical stresses.
From an export perspective, the sheets are supplied with comprehensive certification, including mill test reports and compliance with international standards such as ASTM A240 and EN 10088. Packaging is designed to protect the material during transit, ensuring it arrives in pristine condition ready for immediate use. The global availability and adherence to stringent quality controls make this product a reliable option for industrial buyers seeking robust stainless steel solutions.

Manufacturing Process & Heat Treatment of Duplex 2101 Sheet
Annealing
Annealing of Duplex 2101 sheets is performed to relieve internal stresses and enhance ductility. This process involves heating the material to a temperature range of 1020-1100°C, followed by a controlled cooling process. The annealing cycle helps in achieving a uniform microstructure, which is essential for the subsequent processing steps.
Forging
The forging of Duplex 2101 involves shaping the material at elevated temperatures, typically between 1100-1200°C. This process improves the mechanical properties of the steel by refining the grain structure and enhancing strength. The forged sheets are then cooled in air to room temperature.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020-1100 | Oil | To increase hardness and strength |
| Tempering | 600-800 | Air | To reduce brittleness and improve toughness |
| Solution Treatment | 1020-1100 | Water | To dissolve precipitates and enhance corrosion resistance |
The manufacturing and heat treatment processes of Duplex 2101 sheets are critical in achieving the desired mechanical properties and corrosion resistance for various industrial applications. Proper adherence to these processes ensures high-quality performance in service.
