Duplex Steel 2205 Sheet & Plate

Overview of Duplex Steel S31803 / S32205 Sheet & Plate

Duplex steel is a stainless steel alloy composed of a balanced microstructure—approximately equal parts of austenite and ferrite phases. This dual-phase composition offers a unique combination of strength and corrosion resistance, making it a preferred choice across multiple industries. Owing to its high performance, Duplex steel is widely used in applications such as chemical processing, pipelines, marine environments, and other settings with elevated chloride exposure.

Key Features of Duplex Steel S31803 / S32205

Duplex Steel grades S31803 and S32205 are particularly known for their exceptional resistance to general and localized corrosion, including stress corrosion cracking. These grades also provide excellent mechanical strength and durability, even in elevated temperatures and harsh environmental conditions. Additionally, the material is highly weldable—especially in thicker sections—while offering good low-temperature toughness and oxidation resistance. Notably, the strength of grade S31803 surpasses that of conventional austenitic stainless steel grades, making it ideal for structurally demanding applications.
