CastoTig 45660 W

CastoWig 45660 W, Ø 2.5mm, 5.0kg

The NiCu-based weld metal is resistant to cavitation and sliding wear - lubricated and unlubricated. Permissible operating temperature from -80 °C to 425 °C (mixed joints up to 300 °C).
Good corrosion resistance against:

• Water - distilled, neutral, hard, soft; sea water, saline solutions;
• Salts - neutral, alkaline; sodium and calcium chloride, hypochlorides (< 2 % Cl);
• Mineral acids - sulphuric, phosphoric, hydrofluoric, silicic and hydrochloric acid (< 20 %);
• Organic acids - acetic, tartaric, oxalic, citric, formic and fatty acids;
• Caustic alkalis - caustic soda and potassium hydroxide solutions;
• Dry gases - ammonia, chlorine, hydrogen chloride and hydrogen fluoride, fluorine, superheated steam, hydrogen, combustion gases containing sulphur.

Technical data
EN ISO 18274: S Ni 40 60 (NiCu30 Mn 3 Ti)
AWS A5.14: ERNiCu-7
Material no.: 2.4377

Applications
For alloy-like joint welding of
2.4360 - NiCu 30 Fe
as well as for mixed joints with unalloyed and low-alloy steels, e.g:
P 265 G, 17 Mn 4,, S 255 N, S 355 N
and for surfacing these materials.

Typical applications are:
Pipelines, fittings, containers, apparatus, heating coils, evaporation elements, pumps, valve parts, mixer parts, heat exchangers, extraction devices for vapors as well as pickling hooks and baskets from coking plants, the chemical, salt, food and pharmaceutical industries.

Processing instructions
Clean welding areas. Adjust heat conduction during welding to the component, its material and dimensions. Limit the interpass temperature to 150 °C. Ensure a continuous supply of filler material. Form sufficiently for root welds. Use wire brushes made of austenitic CrNi steels.

Welding positions: all, except PG (f)
Type of current: = (-)
Shielding gas: EN ISO 14175 - I1 (100 % Ar)
