Silvershine-309Mo-15:

SILVERSHINE-309Mo-15 is a basic coated all position electrode yielding 25 Cr-12 Ni-2 Mo stainless steel weld deposit. Characterised by excellent all round performance and weld metal properties including high resistance to chemical corrosion and heat.

Identification:Name Printed

Application:NIdeally suited for buffer layer on dissimilar steels, clad steels, joining dissimilar steels such as stainless steels to mild steel or to low alloy steels and welding build-up of turbine runners made out of plain chromium stainless steel. Also for buffer layers before hardfacing.

Notes on usage:

Ensure that electrodes are dry enough. In case of moisture pick-up, redry the electrodes at 300°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°C-60°C.
Clean the joint faces to remove moisture, grease or any foreign matter.
Employ welding current with in the prescribed range.
Keep the arc as short as possible.
Restrict weaving of electrode to within two and a half times of the core wire diameter.
Use stainless steel wire brush for cleaning the weld beads.
