Postalloy® DuraBuild™ 2866-FCO
Postalloy® DuraBuild™ 2866-FCO is a flux-cored, open-arc high chromium-nickel-moly alloy that produces deposits with excellent strength combined with a high degree of toughness. Fully austenitic weld deposits are especially suited for building-up or buffer layers before hardfacing with a more abrasion resistant alloy. Weld deposits work-harden in service and provide outstanding impact resistance. The austenitic structure of the weld deposit provides very good corrosion resistance as well as good scale resistance up to 1600°F (870°C). 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.
