Manufacturing Process & Heat Treatment of Duplex Steel Sheets

Annealing

Annealing of duplex steel sheets is performed at temperatures between 1000°C to 1100°C. This process allows for the reduction of internal stresses and the improvement of ductility and toughness. The sheets are held at the annealing temperature for a specified duration before being cooled down slowly to room temperature, ensuring a uniform microstructure.

Forging

Forging of duplex steel sheets involves heating the material above its recrystallization temperature, followed by mechanical deformation. This process enhances the mechanical properties by refining the grain structure. The typical forging temperature ranges from 1050°C to 1150°C, depending on the specific composition of the duplex steel.

Hardening & Tempering

Process Temperature Range (°C) Quenching Medium Purpose
Hardening 950 - 1050 Oil To increase hardness and strength of the material
Tempering 400 - 700 Air To relieve stresses and improve toughness
Stress Relieving 300 - 600 Air To eliminate residual stresses from prior processing

The combination of these manufacturing and heat treatment processes ensures that duplex steel sheets exhibit optimal mechanical properties, making them suitable for various industrial applications.
