Stainless Steel Pipe
2507 duplex stainless steel is a special ferritic-austenitic duplex stainless steel with excellent corrosion resistance. Comprehensive protection against point corrosion, crevice corrosion and uniform corrosion is guaranteed through the ratio of chromium and molybdenum elements.
Big fire special steel, high strength steel plate, steel industry supply and demand, steel suppliers
2507(UNS S32750) is an ultra-duplex stainless steel containing 25% chromium, 4% molybdenum and 7% nickel. It is designed for demanding applications that require excellent strength and corrosion resistance, such as chemical processes, petrochemicals and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and low coefficient of thermal expansion. High chromium, molybdenum and nickel levels provide excellent resistance to pitting, crevice corrosion and general corrosion.
