Welding products for stainless steel

ESAB has developed a range of lean duplex welding consumables for stainless steel.

The combination of high strength and good corrosion resistance has made lean duplex steels a cost-competitive option in many applications where traditionally AISI 304 and AISI 316L materials have been used. Typical applications are desalination plants, pipes, storage tanks, floodgates and footbridges.

Although most lean duplex stainless steel grades can be welded successfully with standard duplex 2209 type consumables, ESAB believes lean duplex consumables offer a more cost efficient solution while ensuring that good mechanical properties and corrosion resistance are maintained.

To avoid excessive amounts of ferrite in the weld metal they are higher alloyed with austenite promoting elements than the corresponding steel grades.
