Postalloy®
2866-FCO
Description
POSTALLOY® 2866-FCO is a flux-cored, open-arc high chromium-nickel-moly alloy that produces deposits with excellent strength and elongation, combined with a high degree of toughness. Weld deposits work-harden in service and provide outstanding impact resistance. The austenitic structure of the weld deposit provides very good corrosion resistance. It's versatility allows it to be used for joining, as well as a cushion layer prior to hardfacing with a harder, more wear resistant alloy. Use on carbon and alloy steels, stainless and manganese steels and joining dissimilar combinations.
