Applications & Uses of Duplex Steel 2205 Coils

Duplex Steel 2205 Coils, also known as Duplex Steel S32205 Coils, are renowned for their excellent properties that combine the best features of both austenitic and ferritic stainless steels. These coils are highly sought after in various industries due to their superior strength, corrosion resistance, and durability. In this blog, we will explore the numerous applications and uses of Duplex Steel 2205 Coils, highlighting why they are a preferred choice for many industrial applications.

What is Duplex Steel 2205?

Duplex Steel 2205, also known as UNS S32205, is a type of stainless steel that features a dual-phase microstructure comprising approximately 50% austenite and 50% ferrite. This composition provides Duplex Steel 2205 with a number of beneficial properties:

High Strength: Duplex Steel 2205 is significantly stronger than standard austenitic stainless steels.
Corrosion Resistance: The alloy exhibits excellent resistance to general corrosion, pitting, and crevice corrosion.
Toughness: It maintains good toughness and impact strength, even at low temperatures.
Stress Corrosion Cracking Resistance: Duplex Steel 2205 has high resistance to stress corrosion cracking (SCC).

Properties of Duplex Steel 2205 Coils

Before delving into the applications, it’s essential to understand the key properties that make Duplex Steel 2205 Coils so valuable:

High Strength: Duplex 2205 stainless steel has almost double the yield strength of austenitic stainless steels, therefore it is suitable for high endurance applications.
Excellent Corrosion Resistance: It offers superior resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-rich environments.
Good Weldability and Formability: Despite its high strength, Duplex 2205 can be welded and formed using standard techniques.
High Toughness and Ductility: It maintains good toughness and ductility, even at low temperatures.
