EN ISO 14174 S A AF 2
Applications
EN ISO 14174 S A AF 2 Used for welding of offshore oil/gas, chemical and petrochemical process industries, e.g. pipework systems, flowlines, risers, manifolds etc.
Notes on Usage
Characteristics on Usage
① Duplex stainless steel pipe, plate, fittings and forgings have an approximate 50:50
microstructure of austenite with a ferrite matrix.
② Superflux209 is a inert flux that composition of Si and Mn is hardly changed though welding
condition is changed, and superflux209 is a high basicity flux (the basicity of superflux300 is
1.8).
① Dry the flux at 300~350℃ (572~662℉) for 60 minutes before use.
② Preheat not generally required. Interpass temperature 100~150℃ max, heat input in the range
1.0 ~ 1.5KJ/min-depending on material thickness.
