RAAJSAW-A2 (AWS A5.23 EA2)

Copper coated continuous solid wire for SA welding.

CLASSIFICATION : AWS : SFA/A 5.23 EA2, DIN 8557 : S2Mo

CHARACTERISTICS     :  RAAJSAW-A2 is used for submerged arc welding unalloyed
                                           And low alloy steels with impact requirements higher than
                                           Those obtainable with mild steel filler wires.

APPLICATION : Suitable for welding two run technique with medium and high
Tensile steels.
