SUPER DUPLEX STEEL UNS S32750 ANGLE GENERAL PROPERTIES:
Duplex 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.
SUPER DUPLEX STEEL UNS S32750 ANGLE APPLICATION:
- 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
SUPER DUPLEX STEEL UNS S32750 ANGLE STRESS COROSSION CRACKING:
- Duplex structure of 2507 provides excellent resistance to chloride stress corrosion cracking (SCC).
- Superior to 2205 in corrosion resistance and strength.
- 2507 is especially useful in offshore oil and gas applications and in wells with either naturally high brine levels or where brine has been injected to enhance recovery.
