Duplex Steel UNS S32205 Sheets, also known as duplex stainless steel or 2205 stainless steel, are a type of stainless steel that offers a unique combination of properties derived from both austenitic and ferritic stainless steels. This material is composed of approximately equal parts of austenite and ferrite phases, which contributes to its exceptional strength, corrosion resistance, and durability.

These sheets are highly sought after in various industries due to their remarkable features. Firstly, they exhibit excellent corrosion resistance in diverse environments, including those with high chloride concentrations, acidic conditions, and marine environments. This makes them ideal for use in applications such as chemical processing, oil and gas exploration, and marine engineering. Furthermore, Duplex Steel UNS S32205 Sheets possess superior strength and toughness compared to conventional austenitic stainless steels. This enables them to withstand high mechanical loads and pressures, making them suitable for structural components in construction, pressure vessels, and piping systems.

Manufacturing Process Of Duplex S32205 Sheets

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.
