2507 is a super duplex stainless steel with exceptional resistance to chloride stress corrosion cracking, pitting, and crevice corrosion. It offers yield strength approximately double that of austenitic grades.
Key Properties
Corrosion: Superior resistance to chlorides, seawater, and aggressive acids.
Strength: Yield strength ~550 MPa, double that of 304/316.
Durability: Excellent resistance to erosion, abrasion, and fatigue.
Weldability: Good weldability with proper procedures and filler metals.
Common Applications
Oil & Gas: Subsea pipeline supports, riser clamps, and offshore platform components.
Desalination: High-pressure reverse osmosis system frames and brine heater supports.
Chemical: Sulfuric and phosphoric acid storage tank internals and agitator shafts.
Marine: Seawater cooling system brackets and pump shafts.
