The electrode is especially appropriate for joint welding of austenitic with ferritic materials (black and white welding). The welding deposit is especially crack-resistant due to the high ferrite content.

The electrode should not be welded when coating is damaged. Because of its high melt-off efficiency the electrode is very economical.
