STEELOMATIC-309 Mo L
STEELOMATIC-309 Mo L
DESCRIPTION AND APPLICATIONS: STEELOMATIC – 309 Mo L is a extra low carbon all position electrode depositing radiographic quality 25Cr, 12Ni, 2.5 Mo weld deposits. It has superb operating featured like smooth & stable arc, easy to strike & restrike easily detachable slag. The weld has excellent resistance to intergranular corrosion. Typical application for welding wrought or cast steel of similar composition,
Overlay of Carbon steel, dissimilar steel, austenitic Mn steel, 316 clad steel etc.
NOTES ON USAGE:
- Ensure that electrodes are dry enough. In case of moisture pick-up, ready 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.
