Exaton 25.10.4.L (GTAW)
Exaton 25.10.4.L (GTAW)
Exaton 25.10.4.L is designed for gas shielded arc welding of superduplex stainless steels, such as UNS S32750 (e.g. SAF™ 2507), UNS S32760 and UNS S31803 / S32205 (e.g. SAF™ 2205). It combines high strength with excellent ductility. Exaton 25.10.4.L can also be used for joining UNS S32750 and S32760 to carbon steel or low-alloy steels. Exaton 25.10.4.L can also be used for welding duplex stainless steels when the highest possible corrosion resistance is required. The grade is characterized by excellent resistance to stress corrosion cracking in chloride-bearing environments and excellent resistance to pitting and crevice corrosion. Its corrosion resistance is equal to UNS S31254 (e.g. Alleima® 254SMO™) in most applications.
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.
