Silvershine-317L:

An extra low carbon 19/13 Mo stainless steel electrode with controlled ferrite content of 4 to 9 percent for maximum resistance to stress corrosion cracking, hot cracking, chemical corrosion at high temperature. The weld metal has excellent creep strength and is of radiographic quality. The higher molybdenum content in the weld deposit reduces susceptibility to pitting and increases the strength of weld deposit at elevated temperatures and thus practically eliminates cracking as the weld cools from the molten state to room temperature.

Identification:Name Printed

Application:Welding of 317L type material, in clad fabrication, suitable for welding when heat treatment after welding is impossible. For joining stainless steels to lower alloys and carbon steels.

Notes on usage:

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°C-60°C.
Clean the joint faces to remove moisture, grease or any foreign matter.
Employ welding currents within the prescribed range.
Keep the arc as short as possible.
Restrict weaving of electrode to within two and a half times the core wire diameter.
Use stainless steel wire brush for cleaning the weld beads.
