Lork Group high-quality UNS S32750 is a duplex stainless steel has very good resistance to localized corrosion and stress corrosion cracking in combination with high mechanical strength.
Products Description
Lork Group high-quality UNS S32750 (1.4410 /F53) is a duplex stainless steel 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 high mechanical strength (typically up to 570 MPa yield strength) and good ductility with outstanding corrosion resistance in marine environments. The alloy is supplied with a PREN (Pitting Resistance Equivalent) at >=40.0 which guarantees high resistance to pitting corrosion. In addition, the steel offers high resistance to crevice corrosion and stress corrosion cracking. Ambient and sub-zero (down to minus 50°C) notch ductility is good.
