STEELOMATIC-309 L
STEELOMATIC-309 L
DESCRIPTION AND APPLICATIONS: STEELOMATIC –309 L is a 25 Cr-12 Ni extra low carbon stainless steel electrode having exceptional resistance to sensitisation and intergranular corrosion. It has high resistance to oxidation upto 1100°C. It can be used for joining similar steels, dissimilar metal joining between MS and low alloy steels to stainless and joining straight chrome steels 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.
