ASTM A789 / A790 2507 / 2205 Duplex Steel Pipe With High Tensile Strength

ASTM A789 / A790 2507 / 2205 Duplex Steel Pipe With High Tensile Strength

  Duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels . “ Duplex ” describes a family of stainless steels that are neither fully austenitic , like 304 stainless , nor purely ferritic , like 430 stainless . The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy ( stress corrosion cracking resistance and high strength ) with those of an austenitic alloy ( ease of fabrication and corrosion resistance ) .

   Use UNS32750 super duplex stainless steel pipes can improve corrosion resistance compared to other materials . And super duplex steel pipes have greater tensile and yield strength , good ductility and yield strength , good stress corrosion cracking resistance . Also can help clients reduce their purchase costs , but can gurantee the quality etc .
