It is also suitable for joining stainless steels and nickel alloys for high-temperature service. Exaton Ni60 can also be used for dissimilar joining of stainless steels to nickel alloys and for overlay welding. Applications for Exaton Ni60 are found in cryogenics, components subject to high temperature service up to 980°C (1800°F) such as aircraft ducting, engine exhaust systems, power boilers and recovery boilers and a diversity of seawater applications. The combination of strength and corrosion resistance over a wide range of temperatures is utilized in reaction vessels, line pipe distillation columns and heat exchangers. It is used for Submerged Arc Welding, for example in combination with the flux Exaton 15W.

The alloy is used for joining and overlay welding.

Basic universal electrode with very good welding characteristics, especially designed for welding of carbon steels, carbon manganese steels and fine grained carbon manganese steels with elevated yield strength. Typical field of application is offshore construction.The weld metal alloyed with approximately 0.9% Ni fulfills the requirements on impact toughness at -50°C.The coating is of low moisture absorption type and gives diffusible hydrogen < 4ml per 100 grams of weld metal. OK 48.08 is HIC test compliant as per NACE TM0284 & SSC test compliant as per NACE TM0177.

Exaton 15W is a basic welding flux for submerged arc welding giving good slag removal and a fine bead appearance. Its relatively high basicity makes it suitable for joining of austenitic and duplex stainless steel when high impact strength is desired. Due to its low niobium content burn-off it can be used advantageously with stabilized wire electrodes. Exaton 15W is a high performance welding flux in many joining applications in the chemical, petrochemical and oil&gas industry. It is particularly suited for Exaton range of duplex wire electrodes (e.g. 22.8.3.L/25.10.4.L) due to the highly neutral behavior, which ensures an optimal balanced microstructure. Taking the benefit of its features (not limited to nice bead appearance and self slag release only), it can also be used in combination with NiCrMo-3 and NiCrMo-4 wires for several other applications (i.e. both joining and weld overlay).

Exaton Ni60 welding wire is suitable for joining nickel-chromium-molybdenum nickel alloys and chromiumnickel-molybdenum steels with very high corrosion resistance in oxidizing, aqueous and high temperature environments such as 6Mo-steels, UNS N06625 (2.4856) and corresponding grades. It is also suitable for joining stainless steels and nickel alloys for high-temperature service. Exaton Ni60 can also be used for dissimilar joining of stainless steels to nickel alloys, for overlay welding and is available as both wire and rod. Applications for Exaton Ni60 are found in cryogenics, components subject to high temperature service up to 980°C (1800°F) such as aircraft ducting, engine exhaust systems, power boilers and recovery boilers and a diversity of seawater applications. The combination of strength and corrosion resistance over a wide range of temperatures is utilized in reaction vessels, line pipe distillation columns and heat exchangers.

OK 63.35 Cryo is a low carbon stainless steel electrode with basic coating of the 18Cr12Ni3Mo type. It is suitable for applications where the mechanical requirements are tough. It provides good impact toughness levels. Minimum lateral expansion of 0.38mm requirement is met down to -196°C.

Exaton Ni54 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 Exaton Ni56 is a better matching consumable. Exaton Ni54 are found in components for organic synthesis, wet chlorine gas, hypochlorite, chlorine dioxide atmosphere and ferric and cupric chloride environments. Typical applications for Exaton Ni54 are geothermal wells, HF furnace scrubbers, pesticide production, flue gas scrubber systems, combustion-resistant components for high pressure oxygen service electrolytic galvanizing, plate heat exchangers, phosphoric acid production phosphoric acid production, SO cooling towers and for weld overlays on valves. Exaton Ni54 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. Exaton Ni54 can also be used for dissimilar joining of stainless steels to nickel alloys, for overlay welding and it is used for MIG/MAG welding as well as hot wire TIG and mechanical TIG.
