The main benefit of using duplex stainless steel alloys is that they have superior corrosion resistance properties amongst the other classes. Particularly, the stress related corrosion cracking properties of the duplex s31803 seamless pipe are welcome in industries that process both sulfide or chloride ions. Both sulfide and chloride ions, when deposited on the walls of conventional steel pipes tend to crack because their resistance to such corrosive ions is very little.

On the other hand, the ASTM A790 UNS S31803 Seamless Pipe (Seamless and Welded pipe) was specifically designed to combat issues related to stress corrosion cracking. Apart from being used in such conditions, the uns s31803 pipe suppliers recommend using the alloy as a solution to problems such as pitting, crevice corrosion. In fact, in very oxidizing and acidic solutions, the seamless s31803 pipe will exhibit exceptional resistance to pitting and crevice corrosion.

The PREN or pitting resistance equivalent value of these alloys is higher than alloys like 304 or stainless steel alloy 316. The UNS S31803 Duplex Steel Seamless Pipe exhibits excellent impact toughness even in low temperatures. The alloy gives austenitic stainless steel grades 316 and 317 competition with regards to their cost. Since the yield strength of the alloy is 2 times higher than either grade, the walls of the a790 uns s31803 pipe could be made thinner. This results in not only a lighter weighing s31803 welded pipe, but the cost is also reduced.
