Duplex 2507 with UNS S32750 is a super duplex stainless steel containing 25% Cr, 4% Mo, and 7% Ni resulting in excellent resistance to chloride pitting and crevice corrosion attack, designed for applications which demand exceptional strength and corrosion resistance.
Super Duplex 2507 is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel result in a Pitting Resistance Equivalent number (PREN) of >41, providing pitting and crevice corrosion resistance superior to austenitic and duplex stainless steels in almost all corrosive media, and a Critical Pitting Temperature exceeding 50°C. Duplex 2507 designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. is not recommended for applications which require long exposures to temperatures above 570°F because of the risk of a reduction in toughness. Super Duplex S32750 has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion. The high chromium, molybdenum, and nickel levels provide excellent resistance to pitting, crevice, and general corrosion. 25Cr Super Duplex possesses excellent mechanical properties. Often a light gauge of 2507 material can be used to achieve the same design strength of a thicker nickel alloy. The resulting savings in weight can dramatically reduce the overall cost of fabrication.
