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 950-1050°C followed by a controlled cooling process. This treatment helps to relieve internal stresses, improve ductility, and refine the microstructure, ultimately enhancing the mechanical properties of the steel.
Forging
Forging of Duplex 2101 round bars is typically performed at temperatures between 1100-1300°C. This process involves shaping the metal using compressive forces, which improves the grain structure and results in superior strength and toughness. The forged bars are then cooled gradually to ensure uniform properties throughout the material.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020-1100 | Oil | To increase hardness and strength |
| Tempering | 400-600 | Air | To reduce brittleness and improve toughness |
| Stress Relieving | 600-700 | Air | To eliminate residual stresses |
Through these manufacturing and heat treatment processes, Duplex 2101 round bars achieve optimal mechanical properties, making them suitable for a variety of industrial applications, particularly in environments requiring resistance to corrosion and stress.
