In weld metal in order to avoid too high ferrite content, the filler material must be over-alloyed in nickel which will promote austenite formation. For instance, 2209 (9%Ni) is recommended to weld UR 2205 (5%Ni). This document provides lists of filler materials recommended to weld each duplex grade.(plate) What is the filler in duplex steel?What is the filler in duplex steel?Most duplex stainless steels have an over alloyed filler. For example, 2205 uses 2209 and ZERON 100 uses ZERON 100X. These filler metals are nearly identical in chemistry to the base metal, except for an extra 2% nickel.
