Stainless Steel Duplex 2507 S32750 1.4410 F53
2507 (UNS S32750) alloy is composed of 25% chromium, 4% molybdenum and 7% nickel. It has strong strength and corrosion resistance and is mainly used in chemical processing, petrochemical and subsea equipment. It has strong resistance to chloride corrosion, high thermal conductivity and low thermal expansion coefficient. High chromium, molybdenum and nitrogen content, it has high resistance to pitting corrosion, crevice corrosion and uniform corrosion.
Its impact strength is also high, and 2507 alloy is not suitable for use at temperatures higher than 570°F. Its toughness will be reduced in such an environment for a long time.
