INTERNATIONAL CLASSIFICATIONS |
AWS/ASME A 5.11 E NiCrMo-5
DIN 8555: E 23-UM-250CKNTZ
FEATURES & APPLICATIONS |
Ideally suited for applications involving both heat and corrosion, joining dissimilar nickel alloys or joining these alloys to the stainless steels. For fabrication and repairing chemical vats, retorts, valves and valve bodies, plating tanks, racks and supports, chemical pipelines, evaporators, digestors, hot-work forging dies, furnace racks, hoods and baffles, pumps, valves and controls.
- The most outstanding, universal “one product” for all applications involving resistance to corrosion.
- Deposits are rich in chromium, nickel and molybdenum.
- Offers the best resistance to oxidizing and reducing acids and alkalies even at elevated temperatures.
- Performs on AC as well as DC.
- Extremely tough weld metal that work hardens.
- Also Available in TIG form as product code 6023.

Welding Techniques: Clean area to be welded, removing all contaminating materials and old weld metal. Prepare joint edges. No preheat is usually necessary, nor desirable. Apply using any technique suited to the application – stringer bead, moderate or wide weaving, etc. Allow to cool and remove slag.
