Introduction
2507 Super Duplex Stainless Steel was designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.
CHARACTERISTICS
· High imperviousness to chloride stress consumption splitting
· High Strength
· Better resistance than chloride setting and cleft consumption
· Great general consumption resistance
· Proposed for applications up to 600° F
· Low rate of warm development
· Blend of properties given by austenitic and ferritic structure
· Great weldability and workability
Applications
Oil and Gas industry equipment
Offshore platforms, heat exchangers, process and service water systems, fire-fighting systems, injection and ballast water systems
Chemical process industries, heat exchangers, vessels, and piping
Desalination plants, high pressure RO-plant and seawater piping
Mechanical and structural components, high strength, corrosion-resistant parts
Power industry FGD systems, utility and industrial scrubber systems, absorber towers, ducting, and piping
