ASTM A789 UNS S31803 PED ISO Duplex Stainless Steel Tube
ASTM A789 S32760/S31803 Stainless Duplex Steel Tube PED&ISO
Duplex Steel Tube:
Duplex S31803/2205 is a nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels.
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).
Duplex Steel Tube:
Material Grade S32205 , S31803 , S32304 , S32750, F51 , F53 , 2205 , 2507 etc
