Exaton 25.10.4.L Super Duplex TIG Filler Wire 2.4MM - 5KG
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.

Innovative Corrosion-Resistant Chemistry
Exaton’s advanced alloy chemistry is engineered for exceptional corrosion resistance, achieved through optimised levels of key elements such as chromium (Cr) and molybdenum (Mo).
This innovation not only enhances protection in demanding environments but also improves productivity — allowing for permissible finished chemistry with just a single-layer weld overlay in applications that once required two or even three layers.

SAW Flux with Superior Moisture Protection
Steel drum packaging provides exceptional protection against moisture and reduces the risk of damage during shipping and handling — keeping your flux in perfect condition until it’s ready to use.
Each drum is built for durability and reliability, ensuring consistent weld quality from start to finish. Available in 20–25 kg drums.

SAW Flux Designed to Save
Electroslag welding (ESW) operates much like submerged arc strip cladding — but the real advantage lies in the flux.
ESW flux delivers higher deposition speeds and requires fewer cladding layers, significantly reducing overall operating costs. The result is lower consumable use, less welding time, and greater efficiency — helping you save on both materials and labour.
