UNS S32750 is a super duplex stainless steel designed for
applications that demand exceptional strength and corrosion
resistance. Super Duplex stainless UNS S32750 is a mixed
microstructure of austenite and ferrite (50/50) which has improved
strength over ferritic and austenitic steel grades. Super Duplex
has a higher molybdenum and chromium content which gives the
material greater corrosion resistance than standard duplex grades.
Super Duplex UNS S32750 is the most common super duplex grade in
the market. UNS S32750 is duplex stainless steel specially designed
for service in aggressive chloride-containing environments. It has
very good resistance to localized corrosion and stress corrosion
cracking in combination with high mechanical strength. It is widely
used in oil & gas, hydropower, pressure vessels, pulp & paper,
structural components and chemical tankers.
UNS S32750 Super Duplex (2507) Features
- Super duplex grade with combination of properties given by
austenitic and ferritic structure
- High mechanical strength.
- High resistance to stress corrosion cracking in halide-containing
environments.
- High resistance to pitting and crevice corrosion.
- High resistance to general corrosion.
- High resistance to erosion corrosion and corrosion fatigue.
- Good weldability and workability
- Low rate of thermal expansion
- Suggested for applications up to 600° F
S32750 Super Duplex Chemical Composition
The Chemical Composition of UNS S32750 (2507) consists of 25%
chromium, 4% molybdenum, and 7% nickel. This high molybdenum,
chromium and nitrogen contents provide excellent resistance to
chloride pitting and crevice corrosion attack and the duplex
structure provides 2507 with exceptional resistance to chloride
stress corrosion cracking.

Duplex S32750 possesses excellent mechanical properties. Often a
light gauge of S32750 material can be used to achieve the same
design strength of a thicker nickel alloy. The resulting savings in
weight can dramatically reduce the overall cost of fabrication.
