DevStar 309LMo-FC
AWS: A5.22 (E309LMoT1-4)
Process: FCAW
Alloy Type:
Stainless flux-cored wire for joining dissimilar metals at services below 600°F and for overlay of carbon and low-alloy steels. Molybdenum alloyed at approximately 2.5% to improve high-temperature ductility in dissimilar welds, as well as to increase resistance to pitting corrosion. Carbon is restricted to less than 0.04% to reduce the chance of intergranular corrosion from carbon precipitation.
