Manufacturing Process & Heat Treatment of Duplex 2304

Annealing

Annealing of Duplex 2304 is performed at temperatures between 1050°C and 1150°C. This process helps to relieve internal stresses and improve ductility. The material is held at the annealing temperature for a specific duration before being cooled slowly in air or furnace, ensuring a uniform microstructure.

Forging

Forging of Duplex 2304 involves heating the material to a temperature range of 900°C to 1200°C. This hot working process enhances the mechanical properties by refining the grain structure and improving the overall strength of the material. After forging, the material is air-cooled to room temperature.

Hardening & Tempering

Process Temperature Range (°C) Quenching Medium Purpose
Hardening 1020 - 1100 Oil Increase hardness and strength
Tempering 600 - 800 Air Reduce brittleness and improve toughness
Stress Relieving 300 - 600 Air Minimize residual stresses

The manufacturing and heat treatment processes for Duplex 2304 are critical in achieving the desired mechanical properties and corrosion resistance, making it suitable for various industrial applications.
