2507 Super Duplex Pipe
2507 Super Duplex Pipe
Super Duplex 2507 (UNS S32750) is a high-performance austenitic-ferritic stainless steel known for exceptional strength and superior corrosion resistance,especially in chloride environments,due to its high chromium,molybdenum and nitrogen content,making it ideal for demanding applications in oil & gas,chemical processing and marine industries.
Oil & Gas
Offshore platforms,downhole equipment,pipelines and processing.
Pulp & Paper
Digesters
and bleach washers.
Marine
Shipbuilding,seawater systems and offshore structures.
Desalination
Water treatment and desalination plants.
2507 Super Duplex Pipe
Composition:
Contains approximately 25% Chromium,4% Molybdenum and 7% Nickel,along with Nitrogen.
Corrosion Resistance:
Excellent resistance to pitting,crevice corrosion and chloride stress corrosion cracking (SCC).
Mechanical Strength:
Very high mechanical strength,often allowing for lighter gauge material to achieve the same design strength as thicker nickel alloys.
Thermal Properties:
Good thermal conductivity and low coefficient of thermal expansion.
