Electrodes for Creep Resisting Steels
CROMOTHERME-92 H4R
AWS: SFA 5.5 E9015-B92
EN ISO CODE:
Cromotherme-92 H4R is moisture resistant hydrogen controlled basic coated non synthetic electrode deposits 9Cr - 1Mo and enriched with Niobium, Vanadium, Nitrogen and Tungsten. 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, A387 Gr92, etc.
