Description
Exaton 21.13.3.L is a chromium-nickel-molybdenum strip electrode used for corrosion resistant alloy surfacing with electro-slag welding (ESW) or with submerged arc welding (SAW). In ESW, single layer overlays on carbon- and low alloyed steels of 316/316L composition can be deposited. In SAW, buffer layers of 18%Cr/8%Ni/2%Mo composition can be deposited on carbon- and low alloyed steels before surfacing of second layers with molybdenum containing alloys.– Combined with 19.13.4.L for the second layer it will give 317L weld deposit– Combined with 20.25.5.LCu for the second layer it will give 385 weld deposit– Other combinations and conditions are possible
