309 H

type 
Solid stainless steel filler metal with high carbon content for high temperature applications.
applications 
Cladding on low alloyed steels in case a 18/8 CrNi layer is required in the first layer. Scale resistant up to 1050° C., Buffer layers before hard facing, cladding and joining of similar austenitic steels, specially recommended for use in oxidizing gasses with nitrogen and gasses containing small amounts of oxygen.
Properties 

High mechanical properties and very good weldability, suitable for high operating temperatures up to 1100°C.
