ASME SA789 SAF 2507 UNS S32750 Pipe,Supler Duplex Stainless Steel Tube
2507 Super Duplex Stainless Steel Pipe UNS S32750 Super Duplex Tube
ASTM A789 ASME SA 789 SAF 2507 UNS S32750 , 2507 Super Duplex Pipe is 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.
