Duplex Welded Stainless Steel Pipe / Welded Stainless Steel Tubes 2507/1.4410

Duplex Welded Stainless Steel Pipe / Welded Stainless Steel Tubes 2507/1.4410

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.
