Product Description
Super Duplex S25073 S32750 DIN1.4410 2507 Stainless Steel Plate
Alloy 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications requiring exceptional strength and corrosion resistance. This material is ideal for chemical processing, petrochemical, and seawater equipment applications.
The steel provides excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion. High chromium, molybdenum, and nitrogen levels deliver superior resistance to pitting, crevice, and general corrosion.
