Large Diameter 31803 S2205 Super Duplex Stainless Steel Tube 1mm - 10mm Thickness
Specifications:
S31803 dual phase stainless steel tube characteristics
PREN value 32 ~ 33
The corrosion resistance of the alloy S31803 AISI is between 316L UNS and 6%Mo+N austenitic stainless steel.
The yield strength is stronger than that of 18-8 type austenitic stainless steel by about 2 times.
