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 ) .
Description :
1 . Outer Diameter : 10.3mm - 1219mm
2. Material Grade : S32205 , S31803 , S32304 , S32750, 2205 , 2507 Etc
3 . Wall Thickness : 1.24mm - 59.54mm
4 . Length : As per customer’s requirement
