Manufacturing Process & Heat Treatment of Duplex 2205

Annealing

Annealing of Duplex 2205 pipes is performed to relieve internal stresses and enhance ductility. The process typically involves heating the pipes to a temperature range of 1020-1100°C, followed by a controlled cooling process. This treatment helps in achieving a uniform microstructure and improves overall corrosion resistance.

Forging

Forging of Duplex 2205 involves shaping the metal through mechanical deformation at elevated temperatures. This process enhances the mechanical properties of the material by refining the grain structure, resulting in improved strength and toughness. The typical forging temperature range is between 1100-1200°C.

Hardening & Tempering

Process Temperature Range (°C) Quenching Medium Purpose
Hardening 1040-1100 Water or Oil Increase hardness and strength
Tempering 600-800 Air Reduce brittleness and improve ductility
Stress Relieving 300-500 Air Minimize residual stresses

The combination of these processes ensures that Duplex 2205 pipes achieve optimal mechanical properties and corrosion resistance, making them suitable for various demanding applications in the oil and gas, chemical, and marine industries.
