Description
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.
Standards
ASTM/ASME .......... A240 - UNS S32750
EURONORM............ 1.4410 - X2 Cr Ni MoN 25.7.4
AFNOR.................... Z3 CN 25.06 Az
Applications
- Oil and gas industry equipment
- Offshore platforms, heat exchangers, process and service water
systems, fire-fighting systems, injection and ballast water systems
- Chemical process industries, heat exchangers, vessels, and piping
- Desalination plants, high pressure RO-plant and seawater piping
- Mechanical and structural components, high strength,
corrosion-resistant parts
- Power industry FGD systems, utility and industrial scrubber
systems, absorber towers, ducting, and piping
Specifications
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.
The impact strength is also high. Alloy 2507 is not recommended for
applications which require long exposures to temperatures above
570°F because of the risk of a reduction in toughness.
