Alloy 2507 (UNS S32750) Stainless Steel Round Bar
Alloy 2507 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.
Super Duplex 2507 Stainless Steel Bar
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.
Industries that use Super Duplex include:
- Chemical
- Marine
- Oil and Gas production
- Petrochemical
- Power
- Pulp and Paper
- Water desalinization
Products partially or completely constructed of Super Duplex
include:
- Cargo tanks
- Fans
- Fittings
- Heat exchangers
- Hot water tanks
- Hydraulic piping
- Lifting and pulley equipment
- Propellers
- Rotors
- Shafts
- Spiral wound gaskets
- Storage vessels
- Water heaters
- Wire
