Manufacturing Process & Heat Treatment of Duplex 2101 Flanges

Annealing

Annealing of Duplex 2101 flanges involves heating the material to a temperature range of 950-1100Β°C, followed by controlled cooling. This process helps to relieve internal stresses, improve ductility, and enhance the overall mechanical properties of the steel.

Forging

The forging process for Duplex 2101 flanges is conducted at temperatures between 1100-1300Β°C. This hot working technique improves the grain structure of the material, resulting in enhanced strength and toughness. The flanges are shaped into their final form through a series of mechanical operations.

Hardening & Tempering

Process Temperature Range (Β°C) Quenching Medium Purpose
Hardening 1020-1100 Water or Oil To increase hardness and strength
Tempering 300-600 Air To reduce brittleness and relieve stresses
Final Heat Treatment 800-850 Air To optimize mechanical properties and corrosion resistance

The manufacturing and heat treatment processes of Duplex 2101 flanges are critical to ensuring their performance in various industrial applications, providing excellent corrosion resistance and mechanical strength.
