Silvershine-4462:

SILVERSHINE-4462 has been designed specially for welding of "Duplex Steels" & for joining duplex steels to mild steel. Lime-titania covering to drive the advantage of pleasing operating characteristics on DC (+) as well as AC (70V).Controlled weld chemistry for achieving :the desired level of ferrite. a) high resistance to general corrosion, pitting & stress corrosion with high yield strength (>500 N/mm²)

Notes on usage:

In welding duplex stainless steel, due attention has to be given to control heat-input:
use welding currents within the prescribed range & as low as possible, consistent with plate thickness & proper fusion.
keep the arc as short as possible.
avoid heat build-up minimising weaving of electrode, control interpass temperature at 100°C.
Clean the joint faces of all contamination.
use stainless steel wire brush for cleaning the weld beads.
ensure that electrodes are dry enough. In case of moisture pick-up, redry the electrodes at 250°C for 30 to 60 minutes. Thereafter, either allow the oven to cool slowly to about 60°C or transfer them to a holding oven maintained at 50°-60°C.
