Exaton 27.31.4.LCu (GMAW)

Exaton 27.31.4.LCu (GMAW)

Exaton 27.31.4.LCu is a copper alloyed chromium-nickel-molybdenum filler material for MIG welding of high-alloy austenitic stainless steels, such as UNS S08028 / 1.4563 (e.g. Sanicro 28®). It is also suitable for joining UNS N08825 / 2.4858 (e.g. Sanicro 41®) and other similar materials. Due to its outstanding corrosion properties, Exaton 27.31.4.LCu can be used in the most diverse environments, such as contaminated phosphoric acid, sulphuric acid, nitric acid, sour gas service in the oil & gas industry and chloride bearing seawater. Typical applications are found in heat exchangers, evaporators and transport piping. Exaton 27.31.4.LCu GMAW can also be used for plasma welding and overlay welding using hot wire TIG and mechanical TIG. For mechanical properties of weld overlay using GTAW, please refer to the PDS of Exaton 27.31.4LCu GTAW.

Where To Buy

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.
