Product Description
2507 Super Duplex Steel Plate UNS S32750 DIN 1.4410
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 steel offers excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and low coefficient of thermal expansion. The high chromium, molybdenum, and nitrogen levels provide superior resistance to pitting, crevice, and general corrosion.
