Exaton Ni71
Exaton Ni71 is a covered electrode with basic coating and a normal metal recovery for welding of NiCrFe alloys such as Alloy 600, 800 and 800H. 9%Ni steels as well as nickel-alloyed steels for cryogenic temperature use. It is also used for dissimilar joints such as stainless steel and NiCu alloys to carbon steel and nickel alloys. Exaton Ni71 is characterised by little spatter and very good slag removal. Typical applications are found in constructions to be used at lower temperatures e.g. 3.5%, 5% and 9% Ni steels are used as well as austenitic Cr-Ni stainless steel, especially if the weld metal is to be thermoformed or stress relieved. The alloy can be used in air up to 1200°C (2150°F), in sulphur dioxide atmospheres up to 800°C (1470°F) and in ammonia at the highest process temperature. This alloy is used for surfacing or joining where there are strict requirements on stress corrosion resistance and for high temperature service. The microstructure is fully austenitic.
Highlights
Process
For SAW Stainless Steel Welding in Heavy Duty Environments
Developed from a legacy of over 80 years in specialty alloy filler metals, Exaton (formerly Sandvik Welding Operations) is the leading brand in high-quality, corrosion-resistant filler metals. Products are made for welding stainless steel and nickel alloys in the most demanding environments.
Unbeatable Quality in SAW Wire
Wire quality is consistent from batch to batch in terms of chemistry, mechanical properties and dimensional tolerances. Get consistent welds with no need to trim the parameters.
Innovative Corrosion-Resistant Chemistry
Exaton's innovative chemistry provides high corrosion resistance with increased content of chemical elements such as Cr and Mo. It also delivers productivity improvements, such as permissible finished chemistry with a single layer weld overlay in applications that traditionally required two or even three layers.
SAW Flux with Less Moisture & Damage
Steel drum packaging delivers high moisture resistance and less damage during shipping and handling. This better protects the flux inside. Available in 20-25 kg drums.
SAW Flux that Helps You Save
Electroslag welding is similar to submerged arc strip cladding. The difference, however, is in the flux. ESW flux provides increased speed and fewer cladding layers (weld deposit), resulting in an overall lower cost of operation. Savings are in consumable costs and fewer man hours required.
