Product Description

DUPLEX 2205 / F51 STAINLESS STEEL SPECIFICATION SHEET

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.

Applications

• Chemical processing, transport and storage - pressure vessels, tanks, piping, and heat exchangers
• Oil and gas exploration and processing equipment - piping, tubing, and heat exchangers
• Marine and other high chloride environments
• Effluent scrubbing systems
• Pulp and paper industry - digesters, bleaching equipment, and stock-handling systems
• Cargo tanks for ships and trucks
• Food processing equipment
• Biofuels plants
