Duplex 2507 Corrosion Resistance

2507 Duplex is highly resistant to uniform corrosion by organic acids such as formic and acetic acid. It is alsohighly resistant to inorganic acids, especially if they contain chlorides. Alloy 2507 is highly resistant to carbide-related intergranular corrosion. Due to the ferritic portion of the duplex structure of the alloy it is very resistant to stress corrosion cracking in warm chloride containing environments. Through additions of chromium, molybdenum and nitrogen localized corrosion such as pitting and crevice attack are improved. Alloy 2507 has excellent localized pitting resistance.

What are the characteristics of Duplex 2507?

• High resistance to chloride stress corrosion cracking
• High Strength
• Superior resistance to chloride pitting and crevice corrosion
• Good general corrosion resistance
• Suggested for applications up to 600° F
• Low rate of thermal expansion
• Combination of properties given by austenitic and ferritic structure
• Good weldability and workability
