Sanicro® 54 is a nickel-chrome-molybdenum alloy of type alloy C-22. It is a versatile alloy with excellent wet corrosion resistance in oxidizing and reducing media. It has better overall corrosion resistance than other Ni-Cr-Mo alloys such as alloy UNS N10276 (2.4819) and alloy UNS N06626 (2.4856). However, in severely reducing media alloy UNS N10276 is preferred where Sanicro 56 is a better matching consumable. Applications for Sanicro® 54 are found in aggressively corrosive media such as chlorination systems, geothermal wells, HF furnace scrubbers, pesticide production, phosphoric acid production, SO2 cooling towers and for weld overlays on valves.
Sanicro® 54 is used for joining alloy UNS N06022 (2.4602) and is widely used as overmatching filler material for alloy UNS N10276 (2.4819) and other nickel-chrome-molybdenum alloys for better weld metal properties. It is used for surfacing low alloyed steels.

Weld Metal Characteristics
The following data is typical for non heat treated all-weld metal made by the TIG, MIG or PAW methods using argon as shielding gas.
The microstructure is fully austenitic.
|Yield strength, Rp0.2||MPa||500||-|
|Tensile strength, Rm||MPa||770||-|
|Reduction in area, Z||%||50||-|
|Impact strength, Charpy V||J||150||80|
Recommended welding data
Electrode positive is used to give good penetration in all types of welding joint. The table shows common conditions for MIG welding.
|Wire diameter, mm||Wire feed, m/mm (in./min)||Current, A||Voltage, V||Gas, l/min.(CFH)|
|Spray arc welding|
|1.0 (0.039)||6 - 12 (236-472)||150 - 230||26 - 31||22 (46)|

|Pulsed arc welding 1)|
|1.2 (0.047)||3 - 10 (118-394)||150 - 250||23 - 31||20 (42)|
1) Pulse parameters:
- Peak current 300 - 400 A
- Background current 50 - 150 A
- Frequency 80 - 120 Hz
Shielding gases are used for sufficient protection of the weld pool.
The parameters for TIG welding depend largely upon the base metal thickness and the welding application. Electrode negative and a shielding gas of argon or helium should be used to prevent oxidation of the weld metal.
