STEELOMATIC-318 L
STEELOMATIC-318 L
DESCRIPTION AND APPLICATIONS: STEELOMATIC –318 L is an electrode giving Cb-stabilised extra low-carbon 10Cr-12 Ni-2.3 Mo weld metal having exceptional resistance to halide attack and inter granular corrosion. The electrode operates with a quite stable arc, and beads are smooth, finely rippled and uniform The ferrite content of the weld metal is controlled to give adequate crack resistance. The electrode is used for welding AISI 316, 316-L, 316 Ti and 318 Steels and their equivalent grades.
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.
