Manufacturing Process & Heat Treatment of Duplex 2101 Round Bar
Annealing
The annealing process for Duplex 2101 round bars involves heating the material to a temperature range of 950°C to 1050°C, followed by a controlled cooling process. This treatment helps to relieve internal stresses, enhance ductility, and improve overall workability of the steel, making it suitable for further processing and applications.
Forging
Forging of Duplex 2101 round bars is conducted at high temperatures, typically between 1100°C and 1250°C. This process improves the mechanical properties of the steel through deformation, resulting in a refined grain structure that enhances strength and toughness. The forged bars are then allowed to cool gradually to avoid cracking and ensure uniform properties.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Oil or Water | To increase hardness and strength by forming martensite. |
| Tempering | 600 - 800 | Air | To reduce brittleness and improve ductility after hardening. |
| Stress Relieving | 500 - 700 | Air | To relieve residual stresses from the manufacturing process. |
The combination of these manufacturing and heat treatment processes ensures that Duplex 2101 round bars achieve optimal mechanical properties, making them suitable for various industrial applications, including construction and marine environments.
