Exaton 22.9.3.LB is a chromium-nickel-molybdenum-nitrogen covered electrode with basic coating for welding of 22-23%Cr duplex (austenitic-ferritic) stainless steels (e.g. SAF 2205). The basic type of electrode combines good welding properties in all positions and high impact strength at low temperatures. The weld metal is characterized by high strength and very good pitting corrosion resistance as well as very good resistance to stress corrosion cracking in chloride containing media. Exaton 22.9.3.LB is used for welding of duplex and lean duplex stainless steels in service temperatures up to 280°C (536°F). It is also used in applications where good impact toughness properties is required below -40°C. Typical base materials to be welded are ISO: 1.4462, 1.4362, 1.4162, 1.4662, 1.4660 and 1.4417.
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.
