AISI 2205 Stainless Steel Coil – Product Overview

The AISI 2205 Stainless Steel Coil is a high-strength duplex stainless steel grade composed of both austenitic and ferritic stainless steel phases. This combination gives AISI 2205 exceptional strength, excellent resistance to corrosion, and enhanced resistance to stress corrosion cracking, making it one of the most widely used duplex stainless steels for highly demanding applications. It is composed of approximately 22% chromium, 5% nickel, and 3% molybdenum, which contribute to its outstanding resistance to pitting, crevice corrosion, and chloride stress corrosion.

The unique microstructure also gives it superior mechanical properties, such as high tensile strength, good weldability, and good formability. Yuanchi Metal offers premium-quality AISI 2205 stainless steel coils tailored to various specifications, ensuring the material’s performance in highly corrosive and high-strength environments.

Unique Features of AISI 2205 Stainless Steel Coil

• Superior Corrosion Resistance: AISI 2205 is highly resistant to pitting, crevice corrosion, and stress corrosion cracking in aggressive environments, especially in chloride-rich environments.
• High Strength: The duplex microstructure of AISI 2205 provides significantly higher strength than austenitic stainless steels such as AISI 304 and AISI 316, making it ideal for applications requiring high mechanical strength.
• Good Weldability: While AISI 2205 is a duplex steel, it offers excellent weldability with proper procedures, making it suitable for various welding methods including TIG, MIG, and duplex-specific techniques.
• Improved Toughness: This material maintains good toughness at both ambient and cryogenic temperatures, ensuring reliability under varying thermal conditions.
• Magnetic Properties: Due to its ferritic content, AISI 2205 exhibits slight magnetic properties, which can be beneficial in specific industrial applications.
