Product description
Filler metal used for welding high-nickel alloys such as Inconel 600*, Incolloy 800*. Used for heterogeneous assemblies of low-alloy steel with stainless steel or nickel base. Aussu product widely used in the construction of equipment subject to oxidizing and corrosive attack at very high temperatures. Very high toughness at sub-zero temperatures, making it ideal for cryogenic applications on 5% and 9% nickel steels.
