AWS A5.9 ER312
GB/T 29713 S312
Description: The wire is a 29%Cr-9%Ni austenitic-ferritic duplex stainless steel wire. The duplex
structure is maintained even when diluted by a large amount of austenite forming elements, and
therefore has high crack resistance. Can be welded in all positions.
Application: Commonly used for welding cast alloys of similar composition, but can also be used for
carbon steel and stainless steel (especially high nickel stainless steel)
