SDSS S32750 Pipe

Alloy 32750 is a super duplex stainless steel supplied in the solution
annealed condition. As a super duplex stainless steel, it combines the
desirable aspects of both austenitic and ferritic grades. The higher chromium,
molybdenum and nitrogen contents result in a Pitting Resistance Equivalent
number (PREN) of >40, providing pitting and crevice corrosion resistance
superior to austenitic and duplex stainless steels in almost all corrosive
media, and a Critical Pitting Temperature exceeding 50°C.
Main Standards:
ASTM A789 Standard Specification for Seamless and Welded Ferritic/Austenitic
Stainless Steel Tubing for General Service
ASTM A790 Standard Specification for Seamless and Welded Ferritic/Austenitic
Stainless Steel Pipe
ASTM A928 Standard Specification for Ferritic/Austenitic (Duplex) Stainless
Steel Pipe Electric Fusion Welded with Addition of Filler Metal

Advantages of UNS S32750 super duplex
1. Excellent Corrosion Resistance: UNS S32750 SDSS pipes exhibit superior
resistance to a wide range of corrosive environments, including seawater,
acids, and chloride-containing solutions. This characteristic makes them ideal
for applications in offshore oil and gas exploration, chemical processing, and
marine environments.
2. High Strength and Durability: The unique microstructure of 1.4410 super
duplex imparts exceptional mechanical properties, such as high tensile and
yield strength. This makes the pipes suitable for handling high-pressure and
high-temperature conditions, providing long-lasting performance and structural
integrity.
3. Good Weldability: UNS S32750 super duplex is designed with excellent
weldability, allowing for efficient and secure connections. This feature
simplifies installation and maintenance processes, reducing downtime and
overall costs.
4. Cost-Effective Solution: Despite its exceptional properties, super duplex
piping offers a cost-effective alternative to other high-performance alloys.
Its extended service life, reduced maintenance requirements, and resistance to
pitting and crevice corrosion make it an economically viable choice for various
industries.
Applications of UNS S32750 super duplex
1. Oil and Gas: From subsea pipelines to offshore platforms, UNS S32750 SDSS
pipes ensure reliable and long-lasting performance in the harsh and corrosive
environments of the oil and gas industry.
2. Chemical Processing: The excellent resistance of UNS S32750 SDSS to
chemical compounds and acids makes it suitable for applications such as
chemical reactors, heat exchangers, and storage tanks.
3. Marine Industry: UNS S32750 SDSS bars are widely used in shipbuilding,
offshore structures, and desalination plants due to their exceptional corrosion
resistance and strength.
4. Pulp and Paper: The chemical resistance and high strength of uns s32750
round bars make them ideal for handling corrosive chemicals and slurries in the
pulp and paper industry.
