PRODUCT DESCRIPTION
Alloy 2507 is a super duplex stainless steel with 25% Chromium, 4% Molybdenum, and 7% Nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. The steel has excellent resistance to chloride stress corrosion and high thermal conductivity, with a low coefficient of thermal expansion.
The reason Duplex 2507 is utilized is due to its unique properties. On top of its basic corrosion resistance and strength, Duplex 2507 also provides:
Extreme resistance to uniform corrosion
Good resistance to inorganic acids/chlorides
Works with dilute hydrochloric acid
Improved machinability and weldability
High impact strength
