Silvershine-318:

A low carbon 18/13/Mo Nb stabilised electrode with controlled ferrite for maximum resistance to stress corrosion cracking. chemical corrosion and inter-crystalline corrosion. The weld metal has excellent creep strength up to 850°C is of radiographic quality.

Identification:Name Printed

Application:For welding 18/8 Mo Niobium or titanium stabilised steels, such as AISI 318 Grade, paper mill equipment, bleaching equipments, chemical plants, dyeing equipments, pickling plant, heat resisting etc. Also can be used for non-stabilied steels of the type AISI 316 and 317.

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
