SA789 SAF2507 UNS S32750 EN10216-5 1.4410 Super Duplex Stainless Steel Tube
ASTM A789 ASME SA 789 SAF2507 UNS S32750 (EN 10216 - 5 1.4410) Stainless Steel 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.
