Super Duplex 2507 Stainless Steel Plate
UNS S32750
UNS S32750, commonly known as Super Duplex 2507, is very similar to
UNS S31803 Duplex. The difference between the two is the contents
of chromium and nitrogen are higher in the Super Duplex Grade which
in turn creates higher corrosion resistance as well as a longer
lifespan. Super Duplex is composed of between 24% to 26% chromium,
6% to 8% nickel, 3% molybdenum, and 1.2% manganese, with the
balance being iron. Also found in Super Duplex are trace amounts of
carbon, phosphorus, sulfur, silicon, nitrogen, and copper. Benefits
include: good weldability and workability, a high level of thermal
conductivity and low coefficient of thermal expansion, high
resistance to corrosion, fatigue, high resistance to pitting and
crevice corrosion, high resistance to stress corrosion cracking
(especially chloride stress corrosion cracking), high energy
absorption, high strength, and erosion. Essentially, the Duplex
alloys are a compromise; possessing some of the ferritic stress
corrosion cracking resistance and much of the superior formability
of the common austenitic stainless alloys, more cost effectively
than the high nickel alloys.

Applications of S32750 Super Duplex Stainless Steel
Alloy 2507 (UNS S32750) is a super duplex stainless steel with 25%
chromium, 4% molybdenum, and 7% nickel designed for demanding
applications which require exceptional strength and corrosion
resistance, such as chemical process, petrochemical, and seawater
equipment. The steel has excellent resistance to chloride stress
corrosion cracking, high thermal conductivity, and a low
coefficient of thermal expansion. The high chromium, molybdenum,
and nitrogen levels provide excellent resistance to pitting,
crevice, and general corrosion.
The applications of S32750 super duplex stainless steel are:
- Desalination Equipment.
- Chemical process pressure vessels, piping and heat exchangers.
- Marine Applications.
- Flue Gas Scrubbing Equipment.
- Pulp & Paper Mill Equipment.
- Offshore Oil production/technology.
- Oil and gas industry equipment.
