DUPLEX 2507 STAINLESS STEEL

SUPER DUPLEX 2507 STAINLESS STEEL PIPE is a ferritic-austenitic (biphasic) stainless steel that combines the most beneficial properties of many ferritic and austenitic steels because of their high levels of chromium and molybdenum The ability to resist pitting corrosion, crevice corrosion and uniform corrosion.
Product Information
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 nickel levels provide excellent resistance to pitting, crevice, and general corrosion.
