ASTM A790 UNS S32750 Super Duplex Stainless Steels For Waste Water Treatment
As the UNS S32750 Super Duplex Stainless Steel Pipe belongs to super duplex category， it is used for high strength and high corrosive applications. This alloy has 25% chromium in its composition along with 4% molybdenum and 7% nickel， which makes it stronger and much corrosion resistant than the ordinary duplex steel material.
ASTM A790 UNS S32750 Super Duplex Stainless Steels enhance resistance to corrosive and reducing media. A UNS S32750 per Duplex Stainless Steel Pipes also have enhanced resistance to chloride pitting and crevice corrosion. They have great workability and excellent weldability. The UNS S32750 SDSS Pipes have superior strength and good tolerance to stress corrosion cracking. These pipes have a low thermal expansion rate. UNS S32750 Super Duplex SS Pipe have excellent mechanical properties and good toughness.
