Manufacturing Process & Heat Treatment of Duplex Steel Sheets

Annealing

Annealing of duplex steel sheets involves heating the material to a temperature range of 950°C to 1100°C, followed by a controlled cooling process. This step is crucial for relieving internal stresses, enhancing ductility, and improving overall mechanical properties, ensuring the sheets achieve the desired microstructure for optimal performance.

Forging

The forging process for duplex steel sheets typically occurs at temperatures between 1000°C and 1200°C. This hot working process enhances the material's strength and toughness by refining the grain structure. The sheets are shaped and formed into their desired dimensions, ensuring uniformity and consistency across all products.

Hardening & Tempering

Process Temperature Range (°C) Quenching Medium Purpose
Hardening 1000 - 1100 Water To increase hardness and strength
Tempering 600 - 750 Air To reduce brittleness and stress
Solution Treatment 1050 - 1150 Air To achieve a homogeneous microstructure

The combination of these manufacturing and heat treatment processes ensures that duplex steel sheets exported from Oman meet international standards for quality and performance, making them suitable for various industrial applications.
