General Information
Duplex 2507, which is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel. This alloy is designed for applications which require exceptional strength and corrosion resistance;
examples include applications in chemical processing, 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.Duplex 2507 (UNS S32750) in sheet, sheet coil, plate, plate coil, round bar, processed flat bar and tubular products
