AWS: SFA 5.5 E9015-B92
EN ISO CODE:
A low hydrogen non synthetic electrode deposits 9Cr – 0.5Mo - 1.7W and enriched with Niobium, Vanadium and Nitrogen. Tungsten additions provides adequate creep rupture strength at higher steam pressures and temperatures. The controlled addition of alloying elements improves the toughness and weldability. It is designed to weld advanced materials, which are being used to improve thermal efficiency in power plant, refineries etc. Ideal for welding steels of similar composition to achieve adequate creep rupture strength. Some typical materials that are welded with this consumable are A213 T92, A335 P92, A387Gr 92, etc.
