Manufacturing Process Of Duplex S32205 Coils

Reheating Furnace

Reheating furnaces are used in hot rolling mills to heat the steel stock to the rolling temperatures.

Scale Breaker

Slab moves first through a scale breaker, which is a two-high rolling mill with vertical rolls that loosens the furnace scale and removes it with high-pressure water jets.

Finish Rolling

The last stage of the rolling process is cold rolling,


Cooling or Quenching is a process of cooling a metal at a rapid rate.

Skin Pass Mill

This produces high-gloss surfaces and achieves the desired mechanical strip properties such as deep-drawing strength.

Marking & Packing

Proper packaging and labeling not only makes the final product look attractive but also save a huge amount of money by saving the product from wrong handling.

Advantages of Duplex Steel UNS S32205 Coils

Duplex Steel UNS S32205 coils, also known as Duplex 2205 coils, offer several advantages due to their unique composition and properties:

High Strength: Duplex steel coils have a higher strength compared to conventional austenitic or ferritic stainless steels. This makes them suitable for applications where high strength is required, such as in structural components or pressure vessels.

Corrosion Resistance: One of the key advantages of Duplex steel is its excellent corrosion resistance. It offers better resistance to corrosion, especially in harsh environments such as those containing chlorides, compared to austenitic stainless steels. This makes it ideal for use in industries like chemical processing, marine environments, and oil and gas.

Good Weldability: Duplex steel UNS S32205 coils have good weldability, which allows for ease of fabrication and welding during manufacturing processes. This characteristic is crucial in various industries where welding is a common joining method.

High Toughness and Ductility: Duplex steel exhibits high toughness and ductility, which means it can withstand impact loading and deformation without fracturing easily. This property makes it suitable for applications requiring resilience to dynamic loading conditions.

Cost-Effective: Despite its superior properties, Duplex steel UNS S32205 coils can often be more cost-effective compared to other corrosion-resistant alloys such as nickel-based alloys. This makes it an attractive option for applications where cost efficiency is a priority.

Versatility: Due to its combination of properties, Duplex steel is versatile and finds applications across various industries including chemical processing, oil and gas, pulp and paper, desalination plants, and more.
