ASTM A789 / 789M 3 / 4 Inch S32205 Duplex Steel Pipe For Mechanical
Structure Industry
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 ) .
