What is Duplex Stainless Steel UNS31803?
Duplex stainless steel mixed two microstructure that is austenite and ferrite 50/50. It combines the superiority of both ferritic and austenitic steels and has improved strength, Toughness and ductility.
There are two mainly used duplex stainless steel grades, ASTM A815 covers duplex steel grades for buttweld fittings, and ASTM A182 covers material grades for forged pipe fittings.
UNS31803 is a commonly used duplex steel grades for buttweld fittings.
