2507 is a super duplex stainless steel with high chromium, molybdenum, and nitrogen content. It offers exceptional resistance to chloride stress corrosion cracking and pitting, making it ideal for the most aggressive environments.
Key Properties
Corrosion: Superior resistance to chlorides, acids, and seawater.
Strength: High yield strength, approximately double that of austenitic grades.
Durability: Excellent resistance to erosion and abrasion.
Weldability: Good weldability with proper procedures.
Common Applications
Oil & Gas: Subsea pipelines, risers, and offshore platform components.
Desalination: High-pressure reverse osmosis systems and heat exchangers.
Chemical: Tanks and piping for aggressive acids like sulfuric and phosphoric.
Marine: Propeller shafts and pump impellers in seawater.
