Commonly known as 2507, 2507 dual phase steel
Duplex Steel 2507 (UNS S32750) alloy consists of 25% chromium, 4% molybdenum and 7% nickel. It has strong strength and corrosion resistance and is mainly used in chemical processing, petrochemical industry and subsea equipment. It has strong resistance to chloride corrosion, high thermal conductivity and low thermal expansion coefficient. The higher chromium, molybdenum and nitrogen content makes it highly resistant to pitting corrosion, crevice corrosion and uniform corrosion.
