AUTOTHERME Cr-Mo 92
AWS: SFA 5.28 ER90S-B92
EN ISO CODE:
Autotherme Cr-Mo 92 is a copper-coated solid wire for GMAW, available in bright finish, gives smooth flow, stable arc and spatter free under optimum welding conditions. The weld metal content 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 specially 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 where this electrode can be used are P92, Rotor Steel, E 911 steels, GX12 Cr MoWVNbW11etc.
