23/14-322 N

Unitor 23/14-322 N is a rutile-basic high alloyed electrode for welding stainless and acid-resistant steel. It is specially designed for welding stainless compound steel, and as will be seen from the sketch, the unalloyed steel side is welded first using an unalloyed steel electrode, followed by 23/14-322 N on the stainless side. A certain amount of mixing with the unalloyed steel is unavoidable and the electrode is therefore over-alloyed to ensure that the weld will remain stainless.

Stainless steel

Procedure to be followed when welding compound steel.

For this reason, 23/14-322 N can also be used for welding unalloyed steel to stainless steel. This combination should preferably be avoided, but providing an over-alloyed electrode is used the weld will remain stainless. 23/14-322 N provides a weld with good mechanical properties and high crack-resistance. It is suitable for all welding positions and can be used with AC or DC positive polarity. The electrode may also be used for building up a stainless steel surface on ordinary steel.

Welding mild steel to stainless steel.

The same rules as for 18/8-321 N apply with regard to cleaning up the weld.

Best result is obtained using Unitor Pickling Gel to remove discolouration and oxides after welding.
